Compute effect size d
from effect size OR
.
esc_or2d(or, se, v, totaln, es.type = c("d", "cox.d", "g"), info = NULL,
study = NULL)
The effect size as odds ratio.
The standard error of d
. One of se
or v
must be specified.
The variance of d
. One of se
or v
must be
specified.
The total sample size.
Type of effect size that should be returned.
"d"
returns effect size d
"cox.d"
returns effect size d
, based on Cox method
"g"
returns effect size Hedges' g
(see hedges_g
)
String with information on the transformation. Used for the print-method. Usually, this argument can be ignored
Optional string with the study name. Using combine_esc
or
as.data.frame
on esc
-objects will add this as column
in the returned data frame.
The effect size es
, the standard error se
, the variance
of the effect size var
, the lower and upper confidence limits
ci.lo
and ci.hi
, the weight factor w
and the
total sample size totaln
.
