    "# Medical Expenditure Tutorial\n",
    "This tutorial illustrates the use of the AIX360 toolkit to obtain directly interpretable models for predicting medical expenditure of individuals. The two algorithms considered are [Linear Rule Regression (LinRR)](#LinRR), which is a version of Generalized Linear Rule Models (GLRM) for predicting real-valued outcomes, and [Boolean Rule Column Generation (BRCG)](#BRCG). LinRR yields weighted combinations of AND rules that are accurate and have the interpretability of linear models and [generalized additive models](https://en.wikipedia.org/wiki/Generalized_additive_model). It is featured for the task of [expenditure prediction](#expenditure). BRCG gives very simple OR-of-ANDs classification rules and is featured for the task of [high-cost patient identification](#high-cost). The data used is taken from the [Medical Expenditure Panel Survey (MEPS)](https://meps.ahrq.gov/mepsweb/) and is processed as described in the [Data](#data) section.\n",

    "## 1. Use Case\n",
    "The task is to predict the annual healthcare expenditure of individuals based on demographic and socio-economic variables as well as self-reported medical conditions. These predictions are of interest to healthcare \"payers,\" for example insurance companies, employers, governments, or individuals, who are financially responsible for the cost. The input data does not include actual healthcare experience (i.e. claims for services incurred), so the situation is similar to that of enrollment when an individual joins a healthcare plan.\n",
    "\n",
    "Directly interpretable models have a sufficiently simple and transparent form to allow understanding of the behavior of the model as a whole, not just in specific instances (specific individuals). They can identify not only which features are most predictive of the output, but also the nature of the dependence (e.g. its direction and shape). This is most directly illustrated in the [Visualization](#visualize) section. For the present use case, these insights could be compared to a healthcare expert's domain knowledge and/or reviewed by managers before deploying the model, to increase confidence that it will perform as expected. Moreover, the insights could inform interventions to mitigate cost, for example as part of care management. While the models considered here are not causal models and the dependences identified are not necessarily causal, they could be interpreted causally with the help of expert knowledge, or they could suggest causal hypotheses to be tested in future studies."

    "We use AIX360's `MEPSDataset` class to load and pre-process the data. The more notable steps in this processing are 1) restricting race to white and black and ethnicity to non-Hispanic, and 2) removing records with special values (negative integers) for some variables. The selected variables include demographics (e.g. age, gender, marital status), socio-economic factors (education, income, insurance coverage), self-reported health statuses, diagnoses (e.g. heart disease, stroke, diabetes), and health limitations (e.g. cognitive, activity, sensory)."

    "The test R-squared of 14.4% is slightly higher than that of GBRT. More importantly, the LinRR model is directly interpretable (provided that the feature names and values are explained, which we will do in the [Visualization](#visualize) section, see e.g. [[2]](https://meps.ahrq.gov/data_stats/download_data_files_codebook.jsp?PUFId=H181)[[3]](https://meps.ipums.org/meps/index.shtml) for more information on the features). The rule-based and ordinal features included in the linear regression model are shown below along with their coefficients. Being a linear model, feature importance is naturally given by the coefficients and thus the list is sorted in order of decreasing coefficient magnitude (note that coefficients can be positive or negative). The list can be truncated if the user wishes to display fewer features."

Categories 1 and 2 therefore form a kind of [generalized additive model (GAM)](https://en.wikipedia.org/wiki/Generalized_additive_model), i.e. a sum of functions of individual features, where these functions are themselves sums of step function components from category 2 and linear components from category 1. A better visual summary of categories 1 and 2 can be obtained by plotting the univariate functions that make up the GAM, as we do next. We return to the interaction terms in category 3 in the [higher-degree rules](#higher-degree) section."

    "### 3.4. Visualize Generalized Additive Model (GAM) part of LinRR model\n",
    "The `visualize()` method of LinRR is used to plot the GAM part of a LinRR model. To ease interpretation, we plot the component functions of the GAM in groups based on the semantics of the features. We can then examine the sizes and shapes of the dependences on individual features. These can be compared to a domain expert's knowledge to identify behaviors that are expected as well as those that may be surprising. We will attempt to provide such interpretation in this section, although we are not healthcare experts."

    "PCS42 stands for Physical Component Summary and measures physical health status over the four-week period before the MEPS survey date. It is a score computed from 12 responses that assigns higher weights to items such as limitations in activities, pain interfering with work, and difficulty climbing stairs. Lower values indicate poorer health. The plot shows corresponding increases in healthcare cost and especially high cost associated with values under 31."

    "RTHLTH31 represents self-reported health status, with values 1-5 corresponding to \"excellent,\" \"very good,\" \"good,\" \"fair,\" and \"poor.\" The algorithm has given non-zero coefficients only to \"very good\" and \"fair,\" even though one might think that individuals in \"excellent\" health should see a reduction in cost at least as great as those in \"very good\" health. On the other hand, since the statuses are self-reported, \"excellent\" may not necessarily be better than \"very good.\" The absence of a non-zero coefficient for \"poor\" health may be explained by its low frequency in the data. The non-smooth dependence on RTHLTH31 is due in part to treating RTHLTH31 as a categorical variable (see the definition of `colCateg` [above](#process-data)). If smoother behavior is desired, one may try treating values 1-5 of RTHLTH31 as an ordinal variable and handling the value RTHLTH31 == -1 (\"inapplicable\") separately."

In order of importance and as shown below, these are diabetes, cancer, stroke, other heart disease, coronary heart disease, high blood pressure, joint pain in last 12 months, limitation in physical functioning (walking), arthritis, and type of arthritis. Except for WLKLIM31 and ARTHTYPE, a value of 1 means that the condition is present and contributes positively to the prediction as shown. A value of 2 means that the condition is absent, which in the case of WLKLIM31 contributes negatively. The increases in predicted cost due to these conditions (or decrease in the case of WLKLIM31) are all expected and the sizes of the coefficients indicate relative importance. Lastly, ARTHTYPE == -1 means \"inapplicable\", covering both those without arthritis as well as those under age 17 to whom the arthritis question is not applicable."

    "#### Current smoking status\n",
    "The effect of current smoking status (ADSMOK42) is one example of a counter-intuitive finding that may warrant further investigation. A value of 2 indicates that the individual does not currently smoke, to which the model assigns a positive contribution to predicted cost. There may be confounding at work behind this association. For example, the average age of smokers (ADSMOK42 == 1) is 44 while the average age of non-smokers is 49, and older individuals are generally more costly. Furthermore, some individuals who currently do not smoke may have stopped due to poor health."

    "#### Other demographic factors\n",
    "The last four plots show the effects of other demographic variables such as age, race, and geography. \n",
    "\n",
    "The first plot with respect to age (in years) is non-smooth and points to a limitation of the LinRR model. Specifically, since the dependence on age is limited to a linear function (category 1 discussed [above](#categories)) plus step functions corresponding to threshold rules (category 2, not including interaction terms in category 3), the curve is constrained to be piecewise linear with all segments having the same slope and step discontinuities in between. The plot shows that predicted cost first decreases with age until the late 30s, roughly levels off in middle age, and then decreases further after the late 50s. While the first two stages of this behavior are reasonable, the last stage runs counter to the expectation that older individuals (say 60+) experience increasing healthcare costs. This unexpected dependence is mitigated by the second ACTDTY31 plot. While the ACTDTY31 feature is ostensibly about active military duty, a value of 4 actually means that the individual is over age 59 and the question is not applicable. ACTDTY31 == 4 is therefore a proxy for older age and does have a significant positive effect on cost. The non-smooth dependence on AGE31X may also be improved by allowing more general functions in the GAM, for example piecewise linear functions with arbitrary slopes."

    "These higher-degree rules are naturally more difficult to interpret and require more domain expertise to do so. The first three rules are perhaps the simplest. They yield large reductions in predicted cost when certain conditions are absent, with the common element being lack of pregnancy (PREGNT31 != 1). As noted [above](#RTHLTH31), RTHLTH31 != 5 means the individual is not in self-reported \"poor\" health, while ADHDADDX, COGLIM31, and ACTLIM31 refer respectively to attention-deficit/hyperactivity disorder, cognitive limitations, and any activity limitations at work, in housework, or at school. \n",

More cannot be said without knowing what makes the \"serious difficulty seeing\" question inapplicable. In rule 5, values of 8 and 10 for MARRY31X indicate that the individual was widowed or separated during the survey round. Again it is not clear why the absence of these conditions contributes to higher predicted cost, but the last condition PCS42 <= 50.22 does make sense as it corresponds to poor physical health.\n",

Conditioned on this, self-reported health that is less than \"excellent\" (RTHLTH31 != 1) and poorer physical health (PCS42 <= 53.99) result in higher predicted cost. Lastly in rule 7, PHQ242 is a score for depression with higher values corresponding to greater tendency toward depression. PHQ242 != 5 thus indicates the absence of a high value, although not the highest value of 6. POVCAT15 != 5 means that the individual does not have high income (400% above the poverty level) while SOCLIM != -1 means that the question about social limitations is applicable."

BRCG produces a very simple set of rules (also known as an OR-of-ANDs or disjunctive normal form (DNF) rule) for predicting that an individual is high-cost. AIX360 implements a heuristic beam search version of BRCG that is less computationally intensive than the published integer programming version [[4]](http://papers.nips.cc/paper/7716-boolean-decision-rules-via-column-generation). Similar to LinRR, the complexity parameters `lambda0`, `lambda1` penalize the number of rules in the rule set and the number of conditions in each rule. The values of `lambda0`, `lambda1` below provide a good trade-off between accuracy and rule set complexity. Lower values were observed to yield more complex rules but with no improvement in accuracy."

    "In this case, the test accuracy is lower than that of GBCT. The advantage of the BRCG model is its simplicity: It identifies two readily understood subgroups of individuals (not mutually exclusive) predicted to have high cost. The first subgroup consists of individuals with bachelor's degrees (EDRECODE == 15) who have activity limitations affecting work, housework, or school (ACTLIM31 == 1). The second subgroup has limitations in physical functioning (walking, WLKLIM31 != 2), lower physical health status (PCS42 <= 50.22), and some health insurance coverage (INSCOV15 != 3). The first condition, ARTHTYPE != -1, indicates that the question about arthritis type is not inapplicable, which presumably means that the individual does have arthritis and is also 18 years of age or older. One might infer that the common thread between the two subgroups is some sort of physical limitation or poor health coupled with a proxy for higher income (bachelor's degree) or ability to pay (insurance coverage)."

    "## 5. Conclusion\n",
    "This tutorial has shown that the directly interpretable supervised learning algorithms included in AIX360, Generalized Linear Rule Models (GLRM) and Boolean Rule Column Generation (BRCG), are capable of producing accurate and interpretable models for predicting healthcare expenditure. In the case of GLRM (specifically the Linear Rule Regression version), the accuracy is higher than an uninterpretable gradient boosting benchmark while retaining the form of a linear model, the interpretation of which is enhanced by plotting the generalized additive model (GAM) part of the overall model. In the case of BRCG, the accuracy is lower but the model consists of just two rules that are readily understood. We believe that such directly interpretable predictive models (not reliant on post-hoc explanations of individual cases) can be particularly helpful in human-machine collaborations with domain experts and downstream decision-makers."
