\[ \hat{\sigma }^2 = \widehat{\mr{Var}}(~ \log (\mr{RR}_{\scriptstyle \mr{MH}})~ ) = \frac{\sum _ h (n_{h1 \cdot } ~ n_{h2 \cdot } ~ n_{h \cdot 1} - n_{h11} ~ n_{h21} ~ n_ h) / n_ h^2 }{ \left( \sum _ h n_{h11} ~ n_{h2 \cdot } / n_ h \right) \left( \sum _ h n_{h21} ~ n_{h1 \cdot } / n_ h \right) } \]
