est.expDeath | R Documentation |
Estimation of the expected number of deaths in a screening program using the method proposed by Sasieni (2003).
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 |
