Abstract The DISFIT system is a series of programs and subroutines to fit distributions to data. This first volume describes the routines to fit discrete distributions. The distributions included are the binomial, truncated binomial, mixture of two binomials, beta binomial, Poisson, truncated Poisson, mixture of two Poissons, negative binomial, truncated negative binomial, and logarithmic. All parameters are estimated using maximum likelihood techniques. Any of the parameters may be specified instead of estimated. Variances of estimated asymptotic variances of the parameter estimates are also given. Some tests of hypotheses are possible using likelihood ratio tests. This guide contains the descriptions, calling sequences, documentation, and examples for each distribution. The program is written entirely in Fortran, and a listing of the program is in the appendix.
