Function rgsl::statistics::wtss_m

pub fn wtss_m(w: &[f64], wstride: usize, data: &[f64], stride: usize, n: usize, wmean: f64) -> f64

This function returns the weighted total sum of squares (TSS) of data about the weighted mean. For gsl_stats_wtss_m the user-supplied value of wmean is used, and for gsl_stats_wtss it is computed using gsl_stats_wmean.

TSS = \sum w_i (x_i - wmean)²
