In Stata 8's help of "ovtest", it says that the option "rhs" specifies
that powers of the right-hand-side (explanatory) variables are to be
used in the test rather than powers of the fitted value.
But I want to know what powers of the explanatory variables are used
in the test?
I have made a experiment.
If I use 2 regressors in the model, the test will show that it used 6
power-variables in the test regression and the result is
"F(6,...)=...";
If I use 3 regressors in the model, the test will show that it used 9
power-variables in the test regression and the result is
"F(9,...)=...";
and if I use 8 regressors in the model, the test gives the result
"F(18,...)=...".
I don't have the manual of Stata, so I can't read the parts the
concerned in the books.
Thank you~
