Provides posterior summary of non-normal Structural VAR estimation

Provides posterior mean, standard deviations, as well as 5 and 95 percentiles of the parameters: the structural matrix $B$, autoregressive parameters $A$, and hyper parameters.

Usage

# S3 method for class 'PosteriorBSVARMIX'
summary(object, ...)

Arguments

object: an object of class PosteriorBSVARMIX obtained using the estimate() function applied to non-normal Bayesian Structural VAR model specification set by function specify_bsvar_mix$new() containing draws from the posterior distribution of the parameters.
...: additional arguments affecting the summary produced.

Value

A list reporting the posterior mean, standard deviations, as well as 5 and 95 percentiles of the parameters: the structural matrix $B$, autoregressive parameters $A$, and hyper-parameters.
