coef.rma: Model Coefficients for rma Objects

Description

The function extracts the estimated model coefficients, corresponding standard errors, test statistics, p-values, and confidence interval bounds from objects of class "rma".

Usage

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

Arguments

object

an object of class "rma".

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
  corresponding p-value(s).
• ci.lb
  corresponding lower bound of the confidence interval(s).
• ci.ub
  corresponding 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.
