## Estimates Current Cumulative Incidence (CCI) Function

### Description

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

This function estimates the current cumulative incidence (CCI), i.e. the probability that a patient is alive and in any disease remission after initiating his or her therapy.

### Usage

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

### Arguments

`E` |
a matrix with ascending times from therapy initiation to occurrence of individual events (in days); the size of the data matrix is |

`LastContact` |
a vector containing the follow-up time (time from therapy initiation 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` |
