summary.gremlin {gremlin}

Gremlin model summary.

Description

Summarize and print results of linear mixed model fitted with gremlin.

Usage

## S3 method for class 'gremlin'
summary(object, ...)

## S3 method for class 'summary.gremlin'
print(x, digits = max(3, getOption("digits") - 3), ...)

Arguments

object, x

An object of class ‘gremlin’ or ‘summary.gremlin’.

...

Additional arguments to be passed to control the output.

digits

An integer used for number formatting with ‘signif()’.

Value

A list of class summary.gremlin or a printed value to the screen with no return values.

logLik

Model log-likelihood.

formulae

Function call and model fixed, random, and residual formulae.

runtime

A numeric of class ‘difftime’ containing the length of time to run the model. See how this is handled in update.gremlin.

lambda

A logical indicating if the model was transformed to the variance ratio, or lambda scale.

residQuants

A named vector listing summary output for the model residuals.

varcompSummary

Table of variance components and approximate standard errors (calculated from the inverse of the average information matrix). If a (co)variance component is fixed or at the boundary of its parameter space then an NA is returned for the standard error and a column with constraint types is added to the table. Alternative methods (e.g., profile likelihood CIs) should be pursued for obtaining uncertainties associated with fixed or boundary parameters.

varcompSampCor

A matrix containing the sampling correlations of the (co)variance components. Note this is on the underlying nu scale that the model is fitting.

coefficients

Table of fixed effects and standard errors (calculated from the corresponding diagonal elements of the inverse of the coefficient matrix, transformed where necessary).
