A program to compare exponential growth curves via randomization tests has been developed for the one-way analysis-of variance situation. Exponential growth curves of the form Y = a - b exp( - gt) are first fit to each individual's longitudinal data. The parameters from each individual's curve are then input into the randomization program.
