pub fn classify_tests_f(
tstat: &Array2<f64>,
cor_matrix: Option<&Array2<f64>>,
df: &[f64],
p_value: f64,
) -> Array2<i8>Expand description
Classify each contrast per gene as 1 (up), -1 (down) or 0 via the
nested step-down F-test. df is the denominator degrees of freedom,
recycled when length 1 (f64::INFINITY selects the chi-squared limit).
Genes with any NaN t-statistic are returned all-zero: limma sets them NA,
and this i8 port maps NA → 0 to match crate::decidetests.
