Summary. A method has been proposed that gives an exact test and confidence interval for the coefficient of overlap and competition effects. The method is based on Tukey's statistic of nonadditivity. The method is very simple to adopt and can be implemented by regression analysis and analysis of variance programmes in some important cases.
