Deat Stata list,

I would like to run an F test using multiple restrictions on a translog production function with three inputs. This forms a test for homegeneity using the famous F test.

The restrictions that must be jointly imposed are:

1. Beta11+Beta12+Beta13=0
2. Beta21+Beta22+beta23=0
3. Beta31+Beta32+Beta33=0
4. Beta12=Beta21; Beta13=Beta31, Beta23=Beta32

Any one have a clue on how to perform this?

Thank you,
