# extractBoot: Extract Fixed and Random Bootstrapped Parameters

## Description

This generic function extracts the fixed and random components of bootstrapped estimates of an `lqmm`

object.

## Usage

extractBoot(object, which = "fixed")
# S3 method for boot.lqmm
extractBoot(object, which = "fixed")

## Arguments

object

an object of `class`

`boot.lqmm`

.

which

character indicating whether `"fixed"`

or `"random"`

parameters.

## Value

a matrix of bootstrapped estimates.

## Details

The `"random"`

parameters refer to the "raw" parameters of the variance-covariance matrix of the random effects as returned by `lqmm.fit.gs`

and `lqmm.fit.df`

.

## Examples

# NOT RUN {
## Orthodont data
data(Orthodont)
# Random intercept model
fit <- lqmm(distance ~ age, random = ~ 1, group = Subject,
tau = 0.5, data = Orthodont)
fit.boot <- boot(fit)
# extract fixed effects
B <- extractBoot(fit.boot, which = "fixed")
# covariance matrix estimated fixed parameters
cov(B)
# }
