Hi HS,
"Since neither measured nor estimated dissolution percentage should assume negative values there might be a constraint on the error distribution that speaks against using minimisation of sums of squares for estimation of alpha and beta. The applicant should qualify...."
OK, sorry, could not help it. I am unfortunately too unfamiliar with dissolution (or the Excel solver) but do you have a ref. to a work using the equation you have fitted the data to?
Yeah, I love it too.
Merry Xmas.

❝ BTW, Excel is (...) real software.
Yeah, I love it too.
