An example of hierarchical conditional-logistic Bayesian estimation, applied to punishment choice in a public goods game.

Conditional-logistic regression and softmax regression (a.k.a. multinomial logit regression) are covered in Chapter 22 of DBDA2E, but no examples of hierarchical versions are given in that chapter. An example of hierarchical conditional-logistic Bayesi...

Ordinal probit regression: Transforming polr() parameter values to make them more intuitive

In R, the polr function in the MASS package does ordinal probit regression (and ordinal logistic regression, but I focus here on probit). The polr function yields parameter estimates that are difficult to interpret intuitively because they assume a bas...
