Panel data stata
Begin by creating a semester identifier, numbering them in chronological order: sort id startYear startMonth. by id: gen semester=_n. Next convert the date variables into Stata's date format, using months as the base unit: gen start=ym (startYear,startMonth) gen end=ym (endYear,endMonth) format start end %tm.I'm currently conduting a quantile regression analysis on panel data as well and would have some follow-up questions regarding the commands qregpd and xtqreg. For both qregpd (method: Nelder-Meads) and xtqreg, the calculaed estimators for all variables at most of the quantiles are highly insignificant with p-values above 0.7 (I'm pretty sure ...Looking to install solar panels on your property?

1 The basics of panel data We’ve now covered three types of data: cross section, pooled cross section, and panel (also called longitudi-nal). In a panel data set we track the unit of observation over time; this could be a state, city, individual, rm, etc.. To help you visualize these types of data we’ll consider some sample data sets below ...Answer: 1. Identify the variable of interest and the reference. To fix ideas, we will work with a panel dataset, which may be downloaded from the Stata website: This dataset includes economic data on 10 anonymous companies for 20 years, 1935–54. The panel structure has been specified with xtset.
