Description

Analysis of Variance (ANOVA) is a univariate method used to analyse the difference among group means. Multiple test corrected p-values are computed to indicate significance for each feature.

Usage

1
ANOVA(alpha = 0.05, mtc = "fdr", formula, ss_type = "III", ...)

Arguments

alpha

(numeric) The p-value cutoff for determining significance. The default is 0.05.

mtc

(character) Multiple test correction method. Allowed values are limited to the following:

  • "bonferroni": Bonferroni correction in which the p-values are multiplied by the number of comparisons.

  • "fdr": Benjamini and Hochberg False Discovery Rate correction.

  • "none": No correction.

The default is "fdr".

formula

(formula) A symbolic description of the model to be fitted.

ss_type

(character) ANOVA sum of squares. Allowed values are limited to the following:

  • "I": Type I sum of squares.

  • "II": Type II sum of squares.
