Meta-analysis (Point-biserial correlation)

Hello there,

I have trouble performing a correlation analysis using the meta-analysis tool. I have 15 binary variables (metadata) and I would like to perform a point-biserial correlation analysis. The problem is when I want to choose the method of correlation analysis there is no point-biseral method. There are just Pearson, Spearman, and Kendal. I would appreciate it if you could offer any help.
