Hi Statalist, I am trying to estimate a fixed effects regression with many individuals. It is a wage regression, using annual data. The problem is that some people have multiple jobs. This means that some individuals have several observations within each time period, so if I use: xtset piden year, y Stata will issue an error message saying that there are multiple observations within each time period. I can't estimate this model using anything else as I have too many individuals - I have over 155,000 individuals in my model - if I use -areg- or -xi- I will get the "matsize too small" error message. I can't use the user written command -felsdvreg- either as the model comes with importance weights that I must use. If you have any suggestions on what I may do, please fire away! Many thanks in advance. Regards, Ada Ma * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
