Dear stata listers,
I wonder if any one here can share some experience on working with
really large datasets. I m working with a panel dataset (census type
of data) for workers and firms over time. The total number of
observations is about 70 million. I want to estimate  two way fixed
effects models, manually including dummies for regions time and
industries. However with the size of the dataset, the results become
Does anyone know or can direct me to an strategy to deal with "too much data"?
I was thinking about obtaining random samples (say 5%), picking
individuals at random, and keeping them along the whole time they
appear on the sample, and then combining all the results, in a similar
fashion as it is done with Multiple Imputation datasets. But im not
sure how valid would that procedure be.
Any suggestions are welcome,
Thank you.

Fernando Rios
