...result is: yi vi 1 -2.854599 0.8074367 However, if I calculate this manually using the pooled standard deviation formula given in Cooper et al (2009)*, I get an SMD of -2.85625 and a variance of 0.870205. The formula given in Cooper et al for the pooled standard deviation is: Swithin = sqrt(((n1i - 1) * Sd1i^2 + (n2i - 1) * Sd2i^2)/(n1i + n2i -2)) [1.581139 for my example] And the formula for variance is: Vd = (n1i + n2i)/(n1i*n2i) + d^2/(2 *(n1i+n2i)) [1.066667 for my example] Where d is: d = (m1i - m2i)/Swithin [-3.16228 for my example] These are both corrected...
