How can i invert the sign regarding the relationship between two variables in correlation or regression relation, i have the variable of Greed and the variable of ethical behaviour?
if x and y variables show positive correlation, it implies that the inner product of x and y data vector turns out positive, in that situation correlation beetween x and -y will be negative, however for the physical problem you are dealing with the question is whether -y correspond to a realistic variable relevant to the problem.
