If there are multiple controlling variables, say a set of n controlling variables Z = {Z₁, Z₂, .., Zₙ}, then Z in Eq 2.1 should be replaced by Z which denotes a set. The formal definition of partial correlation between X and Y is then. the correlation between the residuals resulting from the ... WebThe partial correlation studied between two variables by keeping the third variable constant is called a first order co-efficient, as one variable is kept constant. Similarly, we can define a second order co-efficient and so on. The partial correlation co-efficient varies between -1 and +1.
