Iím currently assigned a task where I need to investigate if there is any correlation between 15 X-variables (originates from process parameters in the same sub heating group).

I have access to a large data base and we have identified which product runes have generated in the defect outcome. Iím wondering how I can proceed from here without a defined Y variable. Is it possible to assignee nonconformities a given value of 1 and the conformities a given value of 0 and use that as my Y variable?
