y

. replace y and each x variable with a standardized version – i.e. subtract mean and . OLS can be used for relationships that are not strictly linear in x and y by using . of x, y or both; Can use quadratic forms of x; Can use interactions of x variables . the standard error will be smallest when the c's equal the means of the x's .
