Is there a reference article for the weighted spearman correlation?

[KevinMusgrave]

Thanks for making this! Did you come up with weighted spearman method yourself, or is there a reference paper/article that covers this?

Thank you for using it. I didn't come up with them myself, I adapted the formulas from "Weighted and Unweighted Correlation Methods for Large-Scale Educational Assessment: wCorr Formulas" https://files.eric.ed.gov/fulltext/ED585538.pdf

I merely wrote them out differently in this repository as I found them to be more readable this way.

I'll leave this issue open in case other people are curious.
