Hello, I have an unbalanced panel data set. For each id, I’d like to sum all values of x up to the latest time I observe that id, and record the summation to a new variable. How can I do this? Ideally, I’d like to avoid looping as I have a large dataset and I try to speed up the process.
Thank you in advance!
