Some statistics for analysing change in psychiatric research.
Variations in psychological features, including the emergence of, or recovery from, psychiatric disorder, typically involve a long-term process. Consequently, most investigations of these processes will assess the individual or group on a number of occasions, creating complexities in any accompanying statistical analysis. In this paper an approach to analysing such data is introduced, including an extension of the t-test and the analysis of variance.
