Shiny app: Distributions of random variables

There is a new version of my Distributions of Random Variables Shiny app available. This is a cleaned up modern revision of my original 2013 app series involving random variable probability distributions. The primary change is a switch to ggplot2 from base graphics. I have added this app to my shiny-apps GitHub repository so the source code is available, including a script containing all those pesky plotmath expressions.

The app draws and plots samples from various well known discrete and continuous probability distributions, all of which are available in base R with the single exception of the Pareto distribution. To include this distribution, I used the VGAM package. The plots include an overlay of the formula for the selected probability mass or density function.

Available discrete distributions:

• Bernoulli
• Binomial
• Uniform
• Geometric
• Hypergeometric
• Negative Binomial
• Poisson

Available continuous distributions:

• Beta
• Cauchy
• Chi-squared
• Exponential
• F
• Gamma
• Laplace (Double Exponential)
• Logistic
• Log-Normal
• Normal
• Pareto
• t
• Uniform
• Weibull
