I am looking for a tool to demonstrate how the shapes of some basic probability distributions (binomial, hypergeometric, Poisson, exponential and normal) change as a function of their parameters.
I have previously used Matlab's disttool, but I find this cumbersome and visually messy. I could of course make an R script, but for pedagogical reasons I would prefer something with sliders – ideally something the students could play with themselves in their browsers.
I found a Shiny app by Matthew Leonawicz that seemed to be what I'm looking for, but all links to it appear to be dead. The others I have found are all missing the hypergeometric and Poisson distributions.
