 univariate 

Contains a number of functions that serve
two goals. First, to make R more accessible to people migrating
from SPSS by adding a number of functions that behave roughly like
their SPSS equivalents (also see <https://rosettastats.com>). Second,
to make a number of slightly more advanced functions more user
friendly to relatively novice users. The package also conveniently
houses a number of additional functions that are intended to
increase the quality of methodology and statistics in psychology,
not by offering technical solutions, but by shifting perspectives,
for example towards reasoning based on sampling distributions as
opposed to on point estimates.
