Need help troubleshooting a Stata issue. I've been running into dead ends the last few days.



The issue:

I am looking at the relationship of students achieving X1 benchmark and two outcomes (a continuous outcome (Y1) and binary outcome(Y2) using multiple regression and then logistic regression. Also, I need to do all of this once by casewise deletion and another time by multiple imputation.

The end result should produce:

A. Not Imputed (Casewise Deletion) OLS Regression: Y1 on X1

B. Imputed (Casewise Deletion) OLS Regression: Y1 on X1

C. Not Imputed (Multiple Imputation) Multiple Regression: Y1 on X1+X2+X3...

D. Imputed (Multiple Imputation) Multiple Regression: Y1 on X1+X2+X3...

E. Not Imputed (Casewise Deletion) Logit: Y2 on X1

F. Imputed (Multiple Imputation) Logit: Y2 on X1

G. Not Imputed (Casewise Deletion) Logit: Y2 on on X1+X2+X3...

H. Imputed (Multiple Imputation) Logit: Y2 on on X1+X2+X3...




Thus far:
  • A and B estimates are the same (as they should be)
  • C and D estimates are almost the same (as they should be)
  • E and F estimates are very different (something seems wrong, need help)
  • G estimates post fine and seem reasonable
  • H estimates never post, no error message either (loading wheel at bottom cycles for hours, need help)
