| coef.rma {metafor} | R Documentation |
The function extracts the estimated model coefficients, corresponding standard errors, test statistics, p-values, and confidence interval bounds from objects of class "rma".
## S3 method for class 'rma': coef(object, ...)
object |
an object of class "rma". |
... |
other arguments. |
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.
