Prior checks

Usage

prior_check(priors, model_type, type = "density")

Arguments

priors: List of priors for a model, can be retrieved using get_default_prior().
model_type: Type of model the priors will be used for (same as the argument for get_default_prior()).
type: Type of prior check to run, "value" or "prediction". Details below.

Details

The parameter type determines what type of prior check to run. type="value" will plot the prior probability over the parameter value on the original scale. type="predictive" will run a prior predictive plot, where predictions from the model are generated using only prior probabilities (the model when not updated from the data).
