Generate samples from the prior predictive distribution of model parameters

Generates samples from the prior distributions of the model parameters. This is primarily used for prior predictive checks or to generate initial values for MCMC.

Usage

pp_sim(dat, model = "drm", selectivity = NULL, ...)

Arguments

dat

A list containing the data and prior parameters, typically generated by make_data() or make_data_sdm().

model

A character string specifying the model type. Must be either "drm" or "sdm". Defaults to "drm".

selectivity

a numeric vector with the same length as the number of age-groups.

...

parameters passed on to pop_dyn.

Value

A list containing samples drawn from the prior distributions of the model parameters.
