I need intercept in plm model
Hi,R 2.15.2 plm() function on Windows 7
when i perform a plm regression, i can't manage to obtain the intercept, but I need it.it gives me just the beta coefficient.
my formula: fixed <- plm(deltaS ~ L1.deltaS + L2.deltaS, data=Mody_R, index=c("country_id", "date"), model="within")
my output: Coefficients : Estimate Std. Error t-value Pr(>|t|) L1.deltaS -0.063576 0.017950 -3.5419 0.0004031 ***L2.deltaS -0.068272 0.017966 -3.8001 0.0001474 ***---
I tried adding "-0", &q...
