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

"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 confidence interval(s).

ci.ub

upper bound of the confidence interval(s).

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