Hello. I'm trying to fit an econometric model (with panel data). However, each variable has 9 million rows and the calculations take forever. Thus, I took a stratified sample (1.5 million rows per variable) which I used to fit the model. What problems would I meet using this big sample? Are the estimated coefficients reliable? Thank you
