Approximation to incomplete gamma integral with random variates procedures simulate.
Many books in statistics which concerned with the life time distributions does not give sufficient details on the study of c.d.f. of gamma distribution and its tabl So in mis thesis, we consider an approach which approximate the cumulative density function as a limit sum. Further discussion of the approximation of incomplete gamma integral, as well as we consider the approximation of gamma function and its higher derivatives. Tables of the above approximation are represented by the aid of the computer programs.
