non-linear function DEF If the slope of a function depends on the value of X, then f(X) is nonlinear (depends on X1 or X2) - the marginal effect of X is not constant linear function DEF The function f(X) is linear if the slope of f(X) is the same for all values of X Brainpower Read More 0:04 / 0:15 general formula for a nonlinear population regression function the f allows that the conditional expectation of Y given X1i, X2i,...,Xki is a non-linear function of X1 assump
