Abstract : The method of maximum likelihood is used to determine invariant estimates of the unknown location and scale parameters of a sample from the Logistic distribution. The partial derivatives of the likelihood function can not be solved explicitly, therefore the Secant method is used to iteratively determine the roots of the partial derivatives. Using these estimates, modified KolmogorovSmirnov, AndersonDarling and Cramervon Mises statistics are calculated for a given sample. This procedure is repeated 5000 times for sample sizes of n= 5(5)30. The 80th, 85th, 90th, 95th and 99th percentiles of the distribution of each statistic, for each sample size, is then calculated. These values are then used to generate tables of critical values for the Logistic distribution with unknown location and scale parameters. A power comparison between the three tests is performed using samples from various distributions.
