Extracting spatial covariance given only mean and variance
I have the results of an MCMC experiment in the form of a set of means $\mu(\phi,\theta)$ and standard deviations $\sigma(\phi,\theta)$ as a function of spatial coordinates $\phi$ and $\theta$ (in this … Is it possible to use this data to get a decent estimate of spatial covariance (perhaps by assuming a particular form for the spatial covariance), and if so, how? …
