A step-by-step guide to marginalizing over discrete parameters for ecologists using Stan
Everything you might have been afraid to ask about implementing models with discrete parameters in Stan. Written for ecologists that know BUGS, JAGS, or NIMBLE, and want to use Stan. Provides an example by marginalizing over partly observed presence/absence states in a simple occupancy model.
