Calculate Residuals for a ‘reReg’ Fit
Description
Calculates residuals for a joint frailty scale-change model fitted by 'reReg'.
Under the recurrent event model, at each observation time, t,
the residual is calculated as
\mbox{observed number of recurrent events at } t-
\mbox{expected number of recurrent events at} t.
The expected number of recurrent events at t is calculated by the
cumulative rate function at t.
Under the failure time model, the residual is calculated as
\Delta - H(t),
where \Delta is the terminal event indicator and
H(t) is the cumulative hazard function at t.
Usage
## S3 method for class 'reReg'
residuals(object, model = c("recurrent", "failure"), ...)
Arguments
