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 personyears 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 nonparticipants, 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.
