WebJul 14, 2015 · Indeed, because precision is less intuitive than standard deviation, it can be more useful to give standard deviation a uniform prior that spans a wide range. The problem with precision is also that in most cases people are interested in knowing the variance, so you end up with inverting precision. Share Cite Improve this answer Follow Webdistributions (e.g., put the prior on the precision or the variance, use an inverse gamma or inverse chi-squared, etc), which can be very confusing for the student. In this report, we summarize all of the most commonly used forms. We provide detailed derivations for some of these results; the rest can be obtained by simple reparameterization ... cheap sectional local furniture greensboro nc

There are basically two things to be said. The first is that if you look at the density for the multivariate normal distribution (with mean 0 here) it is proportional to. exp ( − 1 2 x T P x) where P = Σ − 1 is the inverse of the covariance matrix, also called the precision.
