Hi, I am developing a frontier model but am unable to predict inefficiency and efficiency values. Below I've copied my instructions:
. xtfrontier frlabreg edu gdppcavg d.act year, ti
[results ommitted for simplicity]
. sort countrynum
. predict fcastti, xb
(36 missing values generated)
. predict inefti, u
not sorted
r(5);
Can you help?
Many thanks
