A personal computer-based system for parallel line analysis of bioassay data

A program is described for symmetric parallel line analysis of bioassay data with a logistic dose-response relationship. Dose-response relationship is transformed to semilog or log-log. A regression line can be calculated for the dose-response curve for standard and test samples, and produces potency estimate of test sample preparation relative to the standard preparation based on parallel-line bioassay statistical methods [3,4], together with detailed analysis of variance, estimates of slope, intercept and chi 2 test which permits a very sensitive test for linearity and parallelism of standard and test sample and facilitates detection of 'outliers', i.e. samples exhibiting non-parallelism. The general comparison of dose-response relationships produced by the program are a feature of particular interest.
