coef.permutest.rma.uni

Extract the Model Coefficient Table from 'permutest.rma.uni' Objects

Description

The function extracts the estimated model coefficients, corresponding standard errors, test statistics, p-values (based on the permutation test), and confidence interval bounds from objects of class "permutest.rma.uni".

Usage

## S3 method for class 'permutest.rma.uni'
coef(object, ...)

Arguments

`object`	an object of class `"permutest.rma.uni"`.
`...`	other arguments.

Value

A data frame with the following elements:

`estimate`	estimated model coefficient(s).
`se`	corresponding standard error(s).
`zval`	corresponding test statistic(s).
`pval`	p-value(s) based on the permutation test.
`ci.lb`	lower bound of the (permutation-based) confidence interval(s).
`ci.ub`	upper bound of the (permutation-based) confidence interval(s).

When the model was fitted with the Knapp and Hartung (2003) method (i.e., test="knha" in the rma.uni function), then zval is called tval in the data frame that is returned by the function.
