coef.egf {epigrowthfit}

Extract Coefficients and Random Effect Covariance Parameters

Description

Extracts the bottom level parameter vector c(beta, theta, b) or a subset. Segments beta, theta, and b contain (respectively) fixed effect coefficients, random effect covariance parameters, and random effect coefficients.

Usage

## S3 method for class 'egf'
coef(object, random = FALSE, full = FALSE, ...)

Arguments

object

an egf object.

random

a logical. If FALSE, then segment b is excluded.

full

a logical. If FALSE, then mapped elements are excluded, and the result is called “condensed”.

...

unused optional arguments.

Value

A numeric vector concatenating beta, theta, and b, without b if random = FALSE and without mapped elements if full = FALSE.

Attribute len is a named integer vector partitioning the result by segment.

Attribute map is a named list of integer vectors i such that that a full segment y and its condensed counterpart x are related by y = x[i], with the exception that i[j] is NA if y[j] is mapped to an initial value. NULL is used in place of an integer vector where x and y are identical.

The result inherits from class coef.egf, which has methods for print, as.list, and labels.
