This is very critical For those who have day variables. We could copy and paste effortlessly into our have Stata to operate using your facts. Should your dataset is private, then give a pretend illustration as an alternative. The 2nd most effective way to elucidate your condition is to implement considered one her explanation of Stata's possess datasets and adapt it for your issue. Illustrations tend to be the vehicle information as well as the have a peek here Grunfeld data (an easy panel dataset). That may be extra give you the results you want and you may not uncover an analog of the issue with this type of dataset. The worst way to elucidate your situation is to explain your data vaguely with no concrete illustration. Note that it will not help us A great deal even for being given your variable names.
