This Shiny App is designed to help users define their priors in a linear regression with two regression coefficients. Using the same example as in the software tutorials on this website, users are asked to specify their plausible parameter space and their expected prior means and uncertainty around these means. The PhD-delay example has been used an easy-to-go introduction to Bayesian inference. In this example the linear and quadratic effect of age on PhD-delay are estimated. Users learn about the interaction between a linear and a quadratic effect in the same model, about how to think about plausible parameter spaces, and about specification of normally distributed priors for regression coefficients. More information about the data and the model can be found here.

The app is self-explanatory. Users can just follow the 4 steps listed in the left side bar and answer the various questions asked.
