I have a list of N people, with two equivalent test performed (A and B), which can have as outcome 0 or 1 (cancer positive or negative). Test A is the accepted gold standard.
Is there any way to find if there are some kind of correlation between both? I found some solutions based on $\chi^2$, but I don't think that can be applied to this case. I also found some related solutions based on ROC curve analysis, but I think is far more complicated than what I need it.
