Thanks for recommending intreg. I was not familiar with this command. When I run the example in the reference manual, the estimated income is not always within the limits of the interval the respondent selected. Using their example and predicting est_income, here are the first 10 observations:
+---------------------------+
| wage1 wage2 est_wage |
|---------------------------|
1. | . 5 4.266946 |
2. | 5 10 7.502522 |
3. | 5 10 10.19239 |
4. | 10 15 8.924339 |
5. | . 5 8.116896 |
|---------------------------|
6. | . 5 10.2202 |
7. | . 5 10.35355 |
8. | 5 10 -2.894233 |
9. | 5 10 13.32243 |
10. | 5 10 9.792462 |
Some estimated values are well outside of the interval. Is it recommended to simply replace these with the interval boundaries?
