Dear all,
I am currently analyzing a model in which the dependent variable is a proportion.
In particular. in order to account for endogeneity, I would like to use the following command taken from https://www3.nd.edu/~rwilliam/stata
code:
fracivp
After the estimates, I need to compute the test of overidentifying restrictions.
Do you know if there is a routine or a code to do it?
For example, after using ivtobit, the test of overidentifying restrictions can be computed by:
code
overid
Many thanks in advance
