β¦ Synopsis
The program estimates the optimal gene-frequencies from observed values of phenotypes by the method of maximumlikelihood. The program does not make assumptions about a specific blood-group-system. This information has to be supplied by input cards.
A straightforward iteration process is used for obtaining initial estimates for the gene-frequencies in question. Then an iterative application of the Newton-Raphson method is used to solve the maximum-likelihood equations.
The program yields the gene-frequencies and their standard deviations, expected values of the phenotypes, expected values of the genotypes. Finally the ehi-square between observed frequencies and (optimal) expected values of phenotypes is computed.
