stan_trace-idealstan-method: Plot the MCMC posterior draws by chain

In saudiwin/idealstan: Robust Measurement with 'Stan'

Plot the MCMC posterior draws by chain

Description

This function allows you to produce trace plots for assessing the quality and convergence of MCMC chains.

Usage

## S4 method for signature 'idealstan'
stan_trace(object, par = "L_full[1]", ...)

Arguments

object	A fitted idealstan model
par	The character string name of a parameter in the model
...	Other options passed on to mcmc_trace

Details

To use this function, you must pass a fitted idealstan object along with the name of a parameter in the model. To determine these parameter names, use the summary function or obtain the data from a plot by passing the return_data=TRUE option to id_plog_legis or id_plot_legis_dyn to find the name of the parameter in the Stan model.

This function is a simple wrapper around mcmc_trace. Please refer to that function's documentation for further options.
