This function returns a data frame containing information on absolute and percentage weights of individual studies contributing to common effect and random effects meta-analysis.
# S3 method for meta
weights(
object,
common = object$common,
random = object$random,
warn.deprecated = gs("warn.deprecated"),
...
)
A data frame with the following variables is returned:
Variable | Definition | Condition |
w.common | absolute weights in common effect model | (if
common = TRUE ) |
p.common | percentage weights in common effect model | (if
common = TRUE ) |
w.random | absolute weights in random effects model | (if
random = TRUE ) |
p.random | percentage weights in random effects model | (if
random = TRUE ) |
An object of class meta
.
A logical indicating whether absolute and percentage weights from the common effect model should be calculated.
A logical indicating whether absolute and percentage weights from the random effects model should be calculated.
A logical indicating whether warnings should be printed if deprecated arguments are used.
Additional arguments (to catch deprecated arguments).
