PURPOSE

Local Regression and Likelihood, Figure 1.1.

SYNOPSIS

This is a script file.

DESCRIPTION

 Local Regression and Likelihood, Figure 1.1.

 A linear regression and plot for Spencer's mortality
 data. Unlike the book, I use locfit for this!

 Setting 'ev','none' means that locfit computes only
 the parametric fit. In this case, 'deg',1; i.e. linear.

CROSS-REFERENCE INFORMATION

This function calls:

lfplot Plot (for one or two dimensions) a locfit() fit.
locfit Smoothing noisy data using Local Regression and Likelihood.

This function is called by:

runbook
