Hi there,

(1)Would you know how to obtain model standard deviations and model autocorrelations of endogenous variables after bayesian estimation.
Ie,Does "oo_.PosteriorTheoreticalMoments.dsge.covariance.Variance.y.y" deliver the variance of y?

(2) Also, would "oo_.PosteriorTheoreticalMoments.dsge.correlation.mean.y" deliver the model implied autocorrelation of the variable y?

Thank you for your help

The fields of

Code: Select all

oo_.PosteriorTheoreticalMoments.dsge

denote the moments you are looking at. The next field provides the statistic for that moment considered.

1.

Code: Select all

oo_.PosteriorTheoreticalMoments.dsge.covariance.Mean.y.y

should be the mean covariance between y and y, i.e. the variance. What you wanted to look at is the variance of the covariance over the MCMC draws.
2. The autocorrelation of y, starting from lag 1, should be in

Code: Select all

oo_.PosteriorTheoreticalMoments.dsge.correlation.Mean.y.y


If you want contemporaneous correlations, you need to use the unstable version with the

Code: Select all

contemporaneous_correlation

option and then look at e.g.

Code: Select all

oo_.PosteriorTheoreticalMoments.dsge.contemporeaneous_correlation.Mean.y.c


to get the correlation between y and c

Thanks
