There is another question. I am going to use these var and covar to
calculate the standard error for other factor (let's say SE(Mij)),
according to a given fomular. But how could I tell if the Mij is
significant at the 5% level, according to the calculated SE(Mij)?
If you mean a linear combination of the coefficients, -help lincom-
If you mean a nonlinear " " ", -help nlcom-
Both will give you an S.E. and confidence interval for an expression
involving the coefficients' values.
