what is the purpose of an empirical bayes estimator which method is used for the estimation of v? which method uses a combination of prior data and estimates? how is a correlation matrix calculated what model is an empirically reliable estimator in? why is the mixed estimate difficult? when using a bayesian formulation it becomes difficult to estimate the correlation matrix (V) of the current observations. which method can i use to calculate the correlation what is a mixed estimate is it possible to estimate a correlation matrix using the mixed estimate when can an estimation of a correlation matrix be performed in parallel which term describes an estimate of a coefficient by using an empirical bayesian formulation? what is the difference between a bayesian formulation and an estimate using ols what is the difference between an empirical and a mixed estimator which of the following is not an empirically-based estimate? what is the difference between a mixed estimate and a bayesian formulation why is an empirical bayes estimator so difficult how to use an empirical method to estimate correlation what kind of method is used to estimate the correlation matrix from the current observations? when to use mixed estimators in linear model
