I am new to STATA and I can use the basic command.
However something that I cannot absolutely understand is how to delete a previous command.
Suppose I have deleted some data doing "keep if male == 0". Now all the data available will be only for female -as 0 means female-.
What though if I want to delete the command "keep if male == 0" and come back to the full data set for both female and male?
I have tried to look for it on the internet and I did find something but it did not work out.
I really need your help...!
Thanks a lot!
