get.est.cr.cox: Compute estimates.
Description
This function uses the crprep function from mstate package to compute coeficients, variance and Breslow baseline estimate of hazards using a cox proportionnal hazard model with counting process notation for competing risks.
For internal use.Usage
get.est.cr.cox( x , data , t1 , status , trans , cens , keep , formula )
Arguments
t1
unique single times at which the survival is to be estimatied.
status
columns indicating the status of observations
trans
transission of interest
keep
covariate to keep (see crprep for details)
formula
an object of class "formula" (or one that can be coerced to that class): a symbolic description of the model to be fitted.
Value
- survAn estimate of the survival function
- sigmaAn estimate of the variance covariance matrix
- betaAn estimate of the coeficients
