I have panel data with the year, id and earn (among others). Now I'm trying to create a line graph for my variable "earn", but only for the ids with more than five observations. That is, if I have more than 10 zeroes or missing values in my time series of 15 years (for each id), I want the whole firm to be excluded from the graph. Does anybody know how I can achieve this?
Many thanks!
Frank
PS: Sorry, if this is an easy question, I'm just getting started :)
