Nonlinear Regression Functions
o plot predicted values as a function of x o compute predicted Y/ X at different values of x Hypotheses concerning degree r can be tested by t- and F-tests on the appropriate (blocks of) variable(s). Choice of degree r o plot the data; t- and F-tests, check sensitivity of estimated effects; judgment. o Or use model selection criteria (later)

opr.princeton.eduMarginal effect (ME) measures the effect on the conditional mean of y of a change in one of the regressors . In the linear regression model, the marginal effect equals the relevant slope coefficient. For non-linear models this is not the case and hence there are different methods for calculating marginal effects.
