\begin{eqnarray*} {\hat{V}_ h}(\hat{Y}_ D) & =& { \frac{{n}_ h(1-f_ h)}{{n}_ h-1} \sum _{i=1}^{n_ h} {(z_{hi\cdot }-\bar{z}_{h\cdot \cdot })^2}} \\ z_{hi\cdot }& =& \sum _{j=1}^{m_{hi}} ~ v_{hij} ~ z_{hij}\\ \bar{z}_{h\cdot \cdot } & =& \left( \sum _{i=1}^{n_ h}z_{hi\cdot } \right) ~ / ~ {n}_ h \end{eqnarray*}
