Discriminant analysis is specifically designed to identify the variables (predictors) that best discriminate between two or more groups (in this case, two sets of individuals). Analysis of variance and analysis of covariance are used to compare means between groups, but do not specifically identify the variables that contribute to group differences. Multiple regression is used to predict an outcome variable based on a set of predictors, but does not necessarily identify the predictors that discriminate between groups.
