Arguments

d

a vector of standardized mean differences for different experiments (not adjusted for small sample size)

f

a vector defining the degrees for each experiment

A

a vector defining the relationship between d and its related t value for each experiment

Value

UnweightedMean The unweighted mean of the small size adjusted standardized mean differences

WeightedMean The weighted mean of the small size adjusted standardized mean differences
