Answer by Xi'an for MCMC with slowly varying Log-Likelihood

If the variations of the target $\pi(\theta|x)\propto f(x|\theta)$ are limited, it means that the data is little informative about $\theta$; this is a poor situation from an inferential viewpoint. it...

MCMC with slowly varying Log-Likelihood

I am using MCMC (Metropolis-Hastings) to simulate values of $\theta$: I have a Log-likelihood (using 10 inputs $x_i$) $$L=-\frac{n}{2}\ln(2\pi)-\frac{1}{2}\sum_{i=1}^n(x_i-\theta)^2$$ The variation...
