Estimation of the expected number of deaths in a screening program using the method proposed by Sasieni (2003).

1 | ```
est.expDeath(contribution, incid, cox, fuzz, covnames)
``` |

`contribution` |
An object of contributions produced by the function |

`incid` |
A matrix containing: the incidences, the value of the covariates and the person-years at risk, in that order. It can be obtained with the function |

`cox` |
An oject of class |

`fuzz` |
Numerical precision is problematic when it comes to test equality between objects. The option |

`covnames` |
An alphanumeric vector containing the names of the covariates used to estimate the survival in the cohort of non-participants, that is, the names of the covariates used to obtain the |

Returns the expected number of deaths

A complete example of usage is provided in the help page of the `screening`

dataset.
