Webbthen you can say that the variable has a significant influence on your dependent variable (y) If this number is < 0.05 then your model is ok. This is a test (F) to see whether all the coefficients in the model are different than zero. If the p-value is < 0.05 then the fixed effects model is a better choice. The coeff of x1 indicates how much WebbHere, the individual effect is α i, and θ t is the time effect. It is a two-way model if both are present. Thus, α i captures effects that are specific to some panel unit but constant over …
