PTCA4CATA | R Documentation |
The PTCA4CATA package provides a set of tools to 1) analyze "Check All That Apply (CATA)" Data; 2) display the results graphically; and 3) perform the correct inferences. In addition to correspondence analysis, Hellinger analysis can also be used. PTCA4CATA uses Partial Triadic Correspondence Analysis (PTCA) to analyze the pseudo-contingency table obtained from a CATA task.
