Easy distribution fitting
GUI univariate distribution fitting and comparison.
First, access CRAN, download R and install. You can install from R console. First install related packages.
install.packages(c("shiny", "tibble", "dplyr", "DT", "readr", "readxl", "R.utils", "fitdistrplus", "ggplot2", "ismev", "evd", "actuar", "FAdist", "extraDistr", "EnvStats", "RcppFaddeeva", "mixtools", "goftest", "rmutil", "PearsonDS", "gsl", "ExtDist", "lmomco", "hydroApps", "normalp", "triangle"))
If packages are installed, it can be started from R console with the following command.
shiny::runGitHub("ezdis", "ToshihiroIguchi")
Host the Shiny application from GitHub in a private network. Enter the following command in R console.
#Port specification
port <- 6500
#Acquire private address information
ipconfig.dat <- system("ipconfig", intern = TRUE)
ipv4.dat <- ipconfig.dat[grep("IPv4", ipconfig.dat)][1]
ip <- gsub(".*? ([[:digit:]])", "\\1", ipv4.dat)
#Host the Shiny application from GitHub
shiny::runGitHub("ezdis", "ToshihiroIguchi", launch.browser = FALSE, port = port, host = ip)
If you are in the private network, you can also launch the Shiny application by entering the URL following Listing on to the browser.
Hosted on shinyapps.io. Use time is limited. https://toshihiroiguchi.shinyapps.io/ezdis/
ezdis can be operated on the browser.
You can load csv, xls, xlsx and xlsm format files by clicking the Browse... button at the top left of the screen.
The first line is the item name, and only the columns with all numerical values are read. However, if there is a sheet of xls, xlsx, xlsm format and all have numerical values, all the numerical values of that sheet are analyzed.
This time, analyze the sample.csv file.
After uploading to ezdis, you can select Use data.
By selecting the item name, the survey will start to find out which distribution fits.
ezdis investigates whether it fits the distribution selected in Setting and displays it in Distribution in ascending order of AIC.
