DiscreteDistribution

A single-file C# discrete distribution class. This class allows you to aggregate samples into integer buckets and perform analysis on the set of samples.

API

Constructors

DiscreteDistribution(List samples)

Constructs a distribution from a set of samples.

DiscreteDistribution(int min, int max)

Constructs an empty distribution with preallocated space.

The class also supports collection initialization.

Other Important Members

int Min

The value of the smallest sample in the distribution.

int Max

The value of the largest sample in the distribution.

this[int key]

Gets or sets the number of samples in the specified bucket.

Add(DiscreteDistribution other)

Adds all the samples in the other distribution to this one.

Add(int sample)

Adds a sample to the distribution.

Add(int sample, int quantity)

Adds a quantity of the same sample to the distribution.

Remove(int sample)

Removes a sample from the distribution.

double GetMean()

Calculates the mean of the distribution.

double GetStandardDeviation()

Calculates the standard deviation of the distribution.

int GetSampleCount()

Returns the total number of samples in the distribution.

string GetHorizontalBarGraph(int maxWidth, string keyFormat)

Produces an ASCII bar graph of the distribution.

• maxWidth: The maximum width of the bars. 0 uses the raw value.
• keyFormat: Format specifier to use to format the key values.
