## Analysis of Variance

### 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

    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. `"III"`: Type III sum of squares. The default is `"III"`.
`...` | Additional slots and values passed to `struct_class`.
