ANOVA test
Perform an ANOVA test on any factors present in a metadata file and/or
metadata-transformable artifacts. This is followed by pairwise t-tests to
examine pairwise differences between categorical sample groups.
Parameters
- metadata : Metadata
- Sample metadata containing formula terms.
- formula : Str
- R-style formula specifying the model. All terms must be present in the
sample metadata or metadata-transformable artifacts and can be
continuous or categorical metadata columns. Formulae will be in the
format "a ~ b + c", where "a" is the metric (dependent variable) and
"b" and "c" are independent covariates. Use "+" to add a variable; "+
a:b" to add an interaction between variables a and b; "*" to include a
variable and all interactions; and "-" to subtract a particular term
(e.g., an interaction term). See
https://patsy.readthedocs.io/en/latest/formulas.html for full
documentation of valid formula operators. Always enclose formulae in
quotes to avoid unpleasant surprises.
- sstype : Str % Choices('I', 'II', 'III'), optional
- Type of sum of squares calculation to perform (I, II, or III).
