summary.asreml {asreml}R Documentation

Summarize an asreml object

Description

A summary method for objects inheriting from class asreml.

Usage

## S3 method for class 'asreml'
summary(object, param = c("sigma", "gamma"),
  coef = FALSE, vparameters = FALSE, ...)

Arguments

object

An asreml object.

param

if "sigma" (the default), random parameter values are reported on the sigma scale only, otherwise, if "gamma", an additional column of variance ratios is returned.

coef

If TRUE (default is FALSE), the coefficients and their standard errors are included in the return object.

vparameters

If TRUE (default is FALSE), the variance parameters are included in the return object in list form.

...

Additional arguments.

Value

A list of class summary.asreml with the following components:

call

The call component from object.

loglik

The loglik component from object.

nedf

The nedf component from object.

sigma

sqrt(object\$sigma2).

varcomp

A dataframe summarising the random parameter vector (object$vparameters). Variance component ratios are included if param="gamma", and a measure of precision is included along with boundary constraints at termination and the percentage change in the final iteration.

aic

Akaike information criterion.

bic

Bayesian information criterion.

distribution

A character string identifying the error distribution(s) if object$deviance != 0.

link

A character string identifying the link function(s) if object$deviance != 0.

deviance

The deviance from the fit if object$deviance != 0.

heterogeneity

Variance heterogeneity (deviance/nedf) if object$deviance != 0.

coef.fixed

A matrix of coefficients and their standard errors for fixed effects if coef=TRUE.

coef.random

A matrix of coefficients and their standard errors for random effects if coef=TRUE.

coef.sparse

A matrix of coefficients and their standard errors for sparse-fixed effects if coef=TRUE.

vparameters

A list of variance structures with matrices converted to full dense form. For ante and chol models the components are given in varcomp and returned in gammas in variance-covariance form.
