Computes posterior draws of structural shock conditional standard deviations

Source: R/compute_conditional_sd.R
compute_conditional_sd.PosteriorBSVAREXH.Rd

Each of the draws from the posterior estimation of models is transformed into a draw from the posterior distribution of the structural shock conditional standard deviations.

Usage

# S3 method for class 'PosteriorBSVAREXH'
compute_conditional_sd(posterior)

Arguments

posterior

posterior estimation outcome - an object of class PosteriorBSVAREXH obtained by running the estimate function.

Value

An object of class PosteriorSigma, that is, an NxTxS array with attribute PosteriorSigma containing S draws of the structural shock conditional standard deviations.
