Function spearman_rank_corr 

pub fn spearman_rank_corr(a: Expr, b: Expr, propagate_nans: bool) -> Expr

Compute the spearman rank correlation between two columns. Missing data will be excluded from the computation.

Arguments

• propagate_nans If true any NaN encountered will lead to NaN in the output. If to false then NaN are regarded as larger than any finite number and thus lead to the highest rank.
