Subject | st: getting realistic fitted values from a regression |
Date | Wed, 21 Jul 2010 14:26:59 -0400 |
Dear STATAlist, I have estimated a regression (OLS) using log of patient travel distance to a hospital predicted by patient, hospital and area characteristics. I am going to report the results as marginal effects that I've computed by obtaining predictions from my estimated regression computed by fixing some variables and keeping others at their original values. However after I compute the predictions, I am getting unrealistically large numbers. When I examined the regression residuals it looks as though the obs with unrealistic fitted values have larger residuals. Is there a way to adjust the regression to better account for this problem?
