pooled_effect
computes the pooled effect size
for a fitted RoBMA.reg and BiBMA.reg object.
Usage
pooled_effect(
object,
conditional = FALSE,
output_scale = NULL,
probs = c(0.025, 0.975),
...
)
Arguments
- object
a fitted RoBMA object
- conditional
show the conditional estimates (assuming that the alternative is true). Defaults to
FALSE
. Only available fortype == "ensemble"
.- output_scale
transform the meta-analytic estimates to a different scale. Defaults to
NULL
which returns the same scale as the model was estimated on.- probs
quantiles of the posterior samples to be displayed. Defaults to
c(.025, .975)
- ...

Details
The meta-regression specification results in the intercept corresponding to the adjusted effect estimate (i.e., adjusting for the effect of moderators). In case of moderators inbalance, the adjusted effect estimate might not be representative of the sample of studies. The pooled effect size function averages the effect size estimate across the moderators proportionately to the moderators levels observed in the data set. Note that there is no Bayes factor test for the presence of the pooled effect (the summary function provides the adjusted effect and the test for the presence of the adjusted effect).
The conditional estimate is calculated conditional on the presence of the adjusted effect (i.e., the intercept).
