Maximum Likelihood Parameter Estimation
Beta Binomial PDF

ASA189 is a FORTRAN77 library which does a maximum likelihood estimation of the parameters of a Beta Binomial PDF.

ASA189 is Applied Statistics Algorithm 189. Source code for many Applied Statistics Algorithms is available through STATLIB.

This algorithm analyzes data that was generated by a beta binomial probability density function, and tries to estimate the values of the parameters that determing that PDF.


ASA189 is available in a FORTRAN77 version and a FORTRAN90 version.
