Running a GMM Estimation on dynamic Panel Model using plm-Package
Hello,
although I searched for a solution related to my problem I didn?t find one,
yet. My skills in R aren?t very large, however.
For my Diploma thesis I need to run a GMM estimation on a dynamic panel
model using the "pgmm" - function in the plm-Package.
The model I want to estimate is: "Y(t) = Y(t-1) + X1(t) + X2(t) + X3(t)" .
