Survival probability conditional on the observed data estimation for interval censored data

```
ICsur(L, R, M, t, method, dist)
```

`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` |
The numeric vector of marker value. |

`t` |
A scaler time point used to calculate the the ROC curve |

`method` |
A character indication type of modeling. This include nonparametric |

`dist` |
A character incating the type of distribution for parametric model. This includes are |

Return a vectors:

`positive `

`P(T<t|L,R,M)`

.

`negative `

`P(T>t|L,R,M)`
