R: Extract the coefficients of a 'tramME' model

coef.tramME {tramME}

R Documentation

Extract the coefficients of a `tramME` model

Description

Extracts the fixed effects coefficents (default behavior), the baseline parameters or all (baseline, fixed and random) coefficients of the model.

Usage

## S3 method for class 'tramME'
coef(object, with_baseline = FALSE, fixed = TRUE, complete = FALSE, ...)

Arguments

`object`	A `tramME` object.
`with_baseline`	If `TRUE`, also include the baseline parameters and the fixed effects parameters from the smooth terms. (Kept for compatibility with `tram`)
`fixed`	If `TRUE`, also include the fixed parameters.
`complete`	If `TRUE`, return all parameters that can be seen as coefficients (baseline, fixed, random) in the `tramME` model. With `complete = TRUE`, `with_baseline = FALSE` and `fixed = FALSE` are ignored. (The behavior of this argument might change in the future).
`...`	Optional parameters (ignored).

Value

Numeric vector of parameter values.

Examples

library("survival")
mod <- SurvregME(Surv(time, status) ~ rx + (1 | litter/rx), data = rats,
                 dist = "exponential", nofit = TRUE)
coef(mod, with_baseline = TRUE)
coef(mod, with_baseline = TRUE, fixed = FALSE)

data("sleepstudy", package = "lme4")
mod2 <- BoxCoxME(Reaction ~ s(Days) + (Days || Subject), data = sleepstudy,
                 nofit = TRUE)
coef(mod2, complete = TRUE)
