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
