This is the first time I post a question in this forum....
I have individual-level and firm-level data that has been aggregated up to industry-level in order to protect the confidentiality of employees and firms. I have the mean and standard deviation for my all of my independent variables from the individual-level data (eg. gender ratio, number of years of education etc) for each of the three size groups of firms: small, medium and large. I also have the mean and standard deviation of my dependent variables which is revenue and year-over-year growth (in terms of revenue and employees).
How do I set up the regression in Stata (given that I have the mean and standard deviation for the aggregated data in different variables)?
