Dear all,
I�m geneticist. Hence, sorry for the dummy questions.
I have to generate a new variable using a set of parameters.
The new variable is generated as follows:
((z^y)/(gamma(y,z)))* integral of x^y-1 * exp^-zx dx from c to infinity,
where
z, y, c are values previously calculated
gamma is the Gamma distribution with parameters y and z.
How do I implement such formula using Stata?
I have already checked "functions" commands, but still feel unsure
regarding the correct implementation.
I�ll be glad for any help. Thanks in advance.
Tiago
