+class RRpsychi(RPackage):
+    """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."""
