Are the mu and s mean and standard deviations of the predictions? I'm not clear on this.
Yes. In the case of the normal the predicted values are themselves z-scores, so you can feed them to the normal CDF, but a bit more work is needed for the logistic (which e.g. does not have unit variance). If you compare predictnl for probit and logit for this model, they do not differ by much.
