In the next edition of this blog, I will return to looking at R’s plotting capabilities with a focus on the ggplot2 package. In the meantime, enjoy using the apply function and all it has to offer.

Discriminant function analysis is very similar to logistic regression , and both can be used to answer the same research questions. [2] Logistic regression does not have as many assumptions and restrictions as discriminant analysis. However, when discriminant analysis’ assumptions are met, it is more powerful than logistic regression. [ citation needed ] Unlike logistic regression, discriminant analysis can be used with small sample sizes. It has been shown that when sample sizes are equal, and homogeneity of variance/covariance holds, discriminant analysis is more accurate. [3] With all this being considered, logistic regression has become the common choice, since the assumptions of discriminant analysis are rarely met. [1] [3]
