Description:
Interval estimates for nonlinear parameters using the linear approximation are sensitive to parameter curvature effects. he adequacy of the linear approximation (Wald) interval is determined using the nonlinearity measures of Bates and Watts (1980), and Clarke (1987b), and the profile t plots of Bates and Watts (1988). hese curvature measures and profile t plot calculations are implemented using the SAS/IML and SAS/NLI procedures.
