## Estimates Current Leukaemia-Free Survival (CLFS) Function

### Description

This is an internal function and is not usually called by user.

This function estimates the current leukaemia-free survival (CLFS) function, i.e. the probability that a patient is alive and in any disease remission after achieving the first disease remission. Only patients who achieved at least one disease remission during their treatment course are used for the estimation of the CLFS function.

### Usage

```
clfs.pest(E, LastContact, Exitus, maxx)
```

### Arguments

`E` |
a matrix with ascending times from achievement of the first disease remission to occurrence of individual events (in days); the size of the data matrix is |

`LastContact` |
a vector containing the follow-up time (time from achievement of the first disease remission to death or to the date of last contact with a patient) |

`Exitus` |
a vector containing the censoring indicators (1..patient died, 0..patient is censored) |

`maxx` |
maximum follow-up time in days |

### Value

a list containing the following elements:

`x` |
days from 0 to maximum follow-up time maxx |

`y` |
CLFS function estimates at each day |
