assumptions_paruv

Determine two assumptions for the parametric comparison tests (i.e. either
<code><a href="/link/t.test?package=micompr&version=1.1.4" data-mini-rdoc="micompr::t.test">t.test</a></code> or <code><a href="/link/aov?package=micompr&version=1.1.4" data-mini-rdoc="micompr::aov">aov</a></code>) for each principal
component, namely: a) univariate normality of each group; b) homogeneity of
variances.

A procedure for comparing multivariate samples associated with
different groups. It uses principal component analysis to convert
multivariate observations into a set of linearly uncorrelated statistical
measures, which are then compared using a number of statistical methods. The
procedure is independent of the distributional properties of samples and
automatically selects features that best explain their differences, avoiding
manual selection of specific points or summary statistics. It is appropriate
for comparing samples of time series, images, spectrometric measures or
similar multivariate observations. This package is described in Fachada et
al. (2016) <doi:10.32614/RJ-2016-055>.
