This Shiny app is meant to let you play around with a few different distributions (Normal, Skew Normal, Cauchy, Skew Cauchy), and check what the effect of different variables (scale, location and shape) on their qq-plot is.

The qq-plots are all a comparison with a default normal distribution (mean=0, sd=1). There is a large slider you can use to track specific percentiles on all graphs. This Shiny app was made for teaching purposes.


This app illustrates the effect of violations of assumptions for the F distribution. It is an update of a TquanT app.
