Beta is defined as covariance of a portfolio (e.g. RISK1) returns with N_cf (cash-flow ...

Stata estimates extensions to generalized linear models in which you can model the structure of the within-panel correlation. This extension allows users to fit GLM-type models to panel data. xtgee offers a rich collection of models for analysts.
