For two-group Discriminant Function Analysis (DFA), SPSS is often considered the most practical choice due to its user-friendly interface and strong support for statistical interpretation, especially in the social sciences. For researchers familiar with coding, R (using the MASS package) offers greater flexibility and reproducibility. Alternatives like SAS and Stata are also reliable, particularly for handling large or complex datasets. Ultimately, the best software depends on the user’s technical preference and the research context.
