✦ Synopsis

We describe a FORTRAN computer program for fitting the logistic distribution function:

Where x represents dose or time, to dose-response data. The program determines both weighted least squares and maximum likelihood estimates for the parameters a and/3. It also calculates the standard errors of a and # under both estimation methods, as well as the median lethal dose (LD50) and its standard error. Dose-response curves found by both fitting methods can be plotted as well as the 95% confidence bands for these lines.

A program, WRANL, is described for the analysis of immunoassays or bioassays which have a logistic dose-response relationship. Responses are transformed to logits and iterative weighted regression analysis is used to obtain log dose-logit response lines for all preparations compared in an assay. Pot

BUMP is a FORTRAN implementation of a modified Jonckheere-Terpstra test, proposed by Simpson and Margolin, to test nonparametrically for a dose-response curve when a downturn is possible at high doses. The Jonckheere-Terpstra statistic is commonly used to test for increasing or decreasing trends in

Two BASIC computer programs using logit transformation for the analysis of S-shaped curves are presented. The first program estimates the median effective dose (ED%) of drugs. A maximum likelihood method similar to Finney's algorithm of probit analysis is applied. The second fits S-shaped curves to
