Extract the fixed effects, randome effects, variance of the
fixed effects, or variance of the random effects from a coxme model.
Usage
# S3 method for coxme
fixef(object, …)
# S3 method for coxme
ranef(object, …)
# S3 method for coxme
vcov(object, …)
# S3 method for coxme
VarCorr(x, …)
Arguments
object
an object inheriting from class coxme
representing the result of a mixed effects Cox model.
x
an object inheriting from class coxme
representing the result of a mixed effects Cox model.
…
some methods for this generic require additional
arguments. None are used in this method.
Value
the fixed effects are a vector and the variance of the fixed
effects is a matrix. The random effects will be a list with one
element for each random effects terms, as will be their variance.
# NOT RUN {rat1 <- coxme(Surv(time, status) ~ rx + (1|litter), rats)
fixed.effects(rat1)
vcov(rat1)
random.effects(rat1)[[1]] #one value for each of the 50 littersVarCorr(rat1)
