)Arguments
- data
Data frame containing the variables used.
- col_names
Vector of two strings to name the output columns for the effect size and it's sampling variance. Default is 'yi' and 'vi'.
- append
Logical. Append the results to
data. Default is TRUE- hedges_correction
Logical. Apply or not Hedges' correction for small-sample bias. Default is TRUE.
