fig7_2

PURPOSE ^

Local Regression and Likelihood, Figure 7.2.

SYNOPSIS ^

This is a script file.

DESCRIPTION ^

 Local Regression and Likelihood, Figure 7.2.

 Conditional Hazard Rate Estimation.
 When hazard rate estimation is performed with multiple x variables,
 the result is an estimate of the conditional hazard rate for the
 first variable, given the levels of the remaining variables.

 The surface plot looks more dramatic than the contour plot in the book!
