Hi,

Is there any way to change elements of the coefficient vector e(b)
obtained after an estimation? For example, suppose I want to
replace the 5th element of the coefficient vector by a value of
2.2; the following does not work:

 . mat e(b)[1,5] = 2.2
 matrix operation not found
 r(501);

I know the following works:

 . mat b0 = e(b)
 . mat b0[1,5] = 2.2

but I want to work with e(b) since I'll later use -predict- to do
some experiments, and I assume that -predict- recognizes e(b)
only.

Thanks for any suggestion.

HJW
