Hello!
I'm working with a panel data, I have daily observations of prices from 01/01/2002 to 31/12/2007 for 35 companies. How can I create a new variable of observations only from april 2002 to april 2003 for every company? and also another one from march 2002 to march 2003? the goal is to have new variables referred to april and march for every year... Thanks a lot!
