I'm also +1 on Pearson, and unsure about concordance ;)

correlation.
Alex, when you mentioned brain imaging, did you mean Pearson
correlation or concordance correlation?
I can't comment on concordance correlation as I was not familiar with it.

Pearson correlation between y_true and y_pred is also a
standard evaluation metric in genomic selection. In a sense,
it can be seen as a ranking measure since y_true and y_pred
don't need to be equal: they only need to be collinear to
achieve perfect correlation.
+1 for adding pearson_correlation_score
I thought we were discussiong the concordance correlation coefficient?
