) -> ExprAvailable on crate features 
rank and propagate_nans only.Expand description
Compute the spearman rank correlation between two columns. Missing data will be excluded from the computation.
ยงArguments
- ddof Delta degrees of freedom
- propagate_nans
If trueanyNaNencountered will lead toNaNin the output. If tofalsethenNaNare regarded as larger than any finite number and thus lead to the highest rank.
