tteICE (version 1.1.2)

coef.tteICE: Coefficients of 'tteICE' objects

Description

This function extracts the coefficients in the Cox models

Usage

# S3 method for tteICE
coef(object, ...)

Value

A list of coefficients of covariates in the working Cox models, stratified by treatment groups. For the treatment policy strategy and composite variable strategy, only one Cox model is fit (for the primary outcome event or the composite event). In these two strategies, coef1 is the coefficients in the treated group, coef0 is the coefficients in the control group. For other strategies, Cox models are fitted for each event (primary outcome event and intercurrent event). In these strategies, coef11 is the coefficients for the primary outcome event in the treatment group, coef10 is the coefficients for the primary outcome event in the control group, coef21 is the coefficients for the intercurrent event in the treated group, coef20 is the coefficients for the intercurrent in the control group.

Arguments

object

A fitted object returned by the function tteICE, surv.tteICE, or scr.tteICE.

Examples

## load data
data(bmt)
bmt = transform(bmt, d4=d2+d3)
A = as.numeric(bmt$group>1)
X = as.matrix(bmt[,c('z1','z3','z5')])
bmt$A = A

fit = tteICE(Surv(t2, d4, type = "mstate")~A|z1+z3+z5,
 data=bmt, strategy="whileon", method='eff')
coef(fit)
