Three apps are currently included in the wiqid package:
"Beta" displays a beta distribution and sliders which allow you to change the parameters. You can also input binomial data and obtain the conjugate beta posterior distribution.
"Gamma" displays a gamma distribution with variable parameters, and can produce the conjugate gamma posterior for Poisson-distributed count data.
"Quadratic" plots a quadratic relationship with variable parameters, showing how the quadratic term can add a hump or hollow to a relationship.
