<div class="fragment"><pre class="comment"> Local Regression and Likelihood, Figure 7.1.

 Estimating the hazard rate for censored survival (or
 failure time) data. Hazard rate estimation is specified
 by 'family','hazard'.

 The censoring indicator variable is passed as the 'cens'
 argument. This should be a vector of 0's and 1's, with 1
 indicating a censored observation, 0 uncensored.

 The 'xlim' argument specifies bounds on the domain of the
 x variable (survival times). Usually, survival times are
 non-negative (lower bound 0), but with theoretically no
 upper bound. The specification [0;10000] gives the lower
 bound of 0, and the upper bound is effectively infinite.

 Author: Catherine Loader

 NEEDS: m argument to lfplot.
 Also, lfplot symbols should distinguish between censored and
 uncensored data points.</pre></div>
