Class: SelectFdr
Filter: Select the p-values for an estimated false discovery rate.
This uses the Benjamini-Hochberg procedure. alpha
is an upper bound on the expected false discovery rate.

Parameters
Parameter | Type | Description |
---|---|---|
opts ? | object | - |
opts.alpha ? | number | The highest uncorrected p-value for features to keep. |
opts.score_func ? | any | Function taking two arrays X and y, and returning a pair of arrays (scores, pvalues). Default is f_classif (see below “See Also”). The default function only works with classification tasks. |
