- <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>
