Compute effect size from Unstandardized Regression Coefficient.
esc_B( b, sdy, grp1n, grp2n, es.type = c("d", "g", "or", "logit", "r", "f", "eta", "cox.or", "cox.log"), study = NULL )
The unstandardized coefficient B.
The standard deviation of the dependent variable.
Treatment group sample size.
Control group sample size.
Type of effect size that should be returned.
Optional string with the study name. Using
The effect size
es, the standard error
se, the variance
of the effect size
var, the lower and upper confidence limits
ci.hi, the weight factor
w and the
total sample size
es.type = "r", Fisher's transformation for the effect size
r and their confidence intervals are also returned.
