This question already has an answer here:
I am looking for a right correlation metric to measure correlation between two vectors. The dimensionality of the vectors is around 100. The first vector has real values as the elements and the second vector has 0,1 values.
Spearman rho is widely used as a correlation metric between two real-valued vectors, but my case is slightly different (0,1 values in one of the vectors). Whether Mann–Whitney U test is more appropriate in my case than Spearman Rho?
I appreciate your help.
