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

With triennial data, let's say your panel variable is called panel and you have a year variable called year. The first step is to -xtset- your data: Code: xtset panel year, interval (3) That will tell Stata that your data is at three-year intervals, so that the "lagged" values refer to the values 3 years ago.To the best of my knowledge and research in the statalist forums, I came to notice that there are several options to regress. Option 1: xtnbreg, fe such as: Code: xtset state year xtnbreg new_firms bank_concentration vc_firms GDP_growth i.year. Option 2: nbreg with dummy vectors. Code:Autocorrelation. Iterated GLS with autocorrelation does not produce the maximum likehood estimates, so we cannot use the likelihood-ratio test procedure, as with heteroskedasticity. However, Wooldridge (2002, 282–283) derives a simple test for autocorrelation in panel-data models. Drukker (2003) provides simulation results showing that the ...Fortunately, it’s possible to detect multicollinearity using a metric known as the variance inflation factor (VIF), which measures the correlation and strength of correlation between the explanatory variables in a regression model.
