Classical Mean-Variance (MV) model has been criticized and it is observed that the use of covariance has sensitivity to the parameter estimation. Thus, the present study set out to formulate a new matrix model, using Bayesian inference as a way to replace covariance in MV, called BMM – Bayesian Matrix Model. To evaluate the model, some hypotheses w...
