Metropolis Hastings proposal for one parameter restricted to less than the other
Suppose I have parameters $\theta_0$ and $\theta_1$ with prior
$$ p(\theta_0,\theta_1)=p(\theta_0|\theta_0<\theta_1)p(\theta_1),$$
that is, $\theta_0$ is less than $\theta_1$. The distributions are …

help interpreting plot of MCMC sample
I am estimating a model using MCMC (Gibbs Sampling). Because of the complexity of the model, I have been running two chains with many iterations.
A plot of the draws for each parameter reveals a spi …

stationarity of vector autoregression and Gibbs sampling
I'm estimating a vector autoregression (VAR) using Gibbs sampling. At each iteration, I'd like to check the coefficients to ensure the VAR is stationary. An older, related question has been posted her …
