condS | R Documentation |

A method to compute the survival function for the interval censored survival data based on a spline function based constrained maximum likelihood estimator. The maximization process of likelihood is carried out by generalized gradient projection method.

```
condS(L, R, M, Delta, t, m)
```

`L` |
The numericvector of left limit of observed time. For left censored observations |

`R` |
The numericvector of right limit of observed time. For right censored observation |

`M` |
An array contains marker levels for the samples. |

`Delta` |
An array of indicator for the censored type, use 1, 2, 3 for event happened before the left bound time, within the defined time range, and after. |

`t` |
A scalar indicates the predict time. |

`m` |
A scalar for the cutoff of the marker variable. |
