Documentation for params common across metabias packages.
Arguments
- yi
A vector of point estimates to be meta-analyzed.
- vi
A vector of estimated variances (i.e., squared standard errors) for the point estimates.
- sei
A vector of estimated standard errors for the point estimates. (Only one of
vi
orsei
needs to be specified).- cluster
Vector of the same length as the number of rows in the data, indicating which cluster each study should be considered part of (defaults to treating studies as independent; i.e., each study is in its own cluster).
- favor_positive
TRUE
if publication bias are assumed to favor significant positive estimates;FALSE
if assumed to favor significant negative estimates.- alpha_select
Alpha level at which an estimate's probability of being favored by publication bias is assumed to change (i.e., the threshold at which study investigators, journal editors, etc., consider an estimate to be significant).
- ci_level
Confidence interval level (as proportion) for the corrected point estimate. (The alpha level for inference on the corrected point estimate will be calculated from
ci_level
.)- small
Should inference allow for a small meta-analysis? We recommend always using
TRUE
.- selection_ratio
Ratio by which publication bias favors affirmative studies (i.e., studies with p-values less than
alpha_select
and estimates in the direction indicated byfavor_positive
).- q
The attenuated value to which to shift the point estimate or CI. Should be specified on the same scale as
yi
(e.g., ifyi
is on the log-RR scale, thenq
should be as well).
