- Censored Local Likelihood
- Author: Catherine Loader
- NEED: this is given problems for unknown reasons. something
- to do with censored observations and the ibeta routine.
- if i replace this by
- res[ZLIK] = th*y-y*log(p)
- res[ZDLL] = y*p
- res[ZDDLL] = y*p*(1-p)
- works fine. Memory leak somewhere??
- also works if i ignore censoring.</pre></div>
