Statistics for psychiatric research
Description
The rpsychi offers a number of functions for psychiatry,
psychiatric nursing, clinical psychology. Functions are
primarily for statistical significance testing using published
work. For example, you can conduct a factorial analysis of
variance (ANOVA), which requires only the mean, standard
deviation, and sample size for each cell, rather than the
individual data. This package covers fundamental statistical
tests such as t-test, chi-square test, analysis of variance,
and multiple regression analysis. With some exceptions, you can
obtain effect size and its confidence interval. These functions
help you to obtain effect size from published work, and then to
conduct a priori power analysis or meta-analysis, even if a
researcher do not report effect size in a published work.
