addPriorGroups: Group together latent parameters by prior distribution.

Description

Add a column to a tidy dataframe of draws that groups parameters by their prior distribution. All parameters with the same prior distribution receive the same index.

Usage

addPriorGroups(drawsDF)

Value

a tidy dataframe of posterior draws. Useful for passing to dagp_plot() or for creating plots using ggplot().

Arguments

drawsDF

the dataframe created by dag_numpyro() where each row represents one draw of MCMC output. Two columns are expected, param - the parameter name, value - the realized value, and a third column, priorGroup, is appended as an integer grouping parameters by their prior distributions. The data for this third column is stored in an environment called cacheEnv when the dag_numpyro() function is called. Any parameters with the same prior end up in the same prior group; used by dagp_plot() to group parameters when plotted.
