Estimasi dai H(4,5) dan variansinya adalah
\(\hat H(4,5) = \frac{2}{{12}} + \frac{1}{{10}} + \frac{2}{9} + \frac{2}{7} = 0,7746\) \(Var\left( {\hat H(4,5)} \right) = \frac{2}{{{{12}^2}}} + \frac{1}{{{{10}^2}}} + \frac{2}{{{9^2}}} + \frac{2}{{{7^2}}} = 0,0894\)

Kepercayaan linear 95% untuk H(4,5) adalah
\({\left( {\hat H(4,5) – 1,96\sqrt {Var(\hat H(4,5))} } \right),\left( {\hat H(4,5) + 1,96\sqrt {Var(\hat H(4,5))} } \right)}\) \(\left[ {\left( {0,7746 – 1,96\sqrt {0,0894} } \right),\left( {0,7746 + 1,96\sqrt {0,0894} } \right)} \right] = (0,1886,{\rm{ }}1,3606)\)
