The 2013 AGRODEP training on "Applied Panel Data Econometrics" was indeed an outstanding experience for me. I learned and revised the various panel data econometric models that are available in applied work. Besides teaching the several panel data models and under what assumptions each model works, professor Parmeter also supported each of his lectures with a real data application using the R software. Though it seemed a very short time, we ended up learning not only several panel data models but also the R and latex softwares. The training was particularly important for me as I am using panel data for my current research. I wish to thank Christopher Parmeter, for having been so generous in giving us his time (until as late as we wanted it) and teaching us such valuable econometric models and softwares. I am also grateful for AGRODEP & IFPRI for giving me the chance to participate in this invaluable training course.
