Witryna22 mar 2024 · Details Currently, the methods for the generic function grangertest only perform tests for Granger causality in bivariate series. The test is simply a Wald test comparing the unrestricted model—in which y is explained by the lags (up to order order) of y and x —and the restricted model—in which y is only explained by the lags of y .

That variance estimator is not valid for fixed effects regression. Until, I think it was, version 13, Stata would calculate that non-valid variance estimator anyway. But from version 13 onward they decided to banish it.

Witryna19 sty 2024 · This plot is used to identify non-linearity in the independent variables of a multiple regression model. The scatter and the slope of the line should look broadly linear in this plot. If it is not then the independent variable you are testing is not linear. All variables in a linear regression should be linear. Witryna7 cze 2015 · You are logging your dependent variable, which means that observations where the dependent variable is equal to zero are dropped. Therefore, dummy variables that are equal to 1 only when the dependent variable is zero will be identically zero in the sample used in the estimation. These will, of course, be dropped because of collinearity.
