<br>
The bounds on reliability for any given time,  <math>T</math> , are estimated by:
<br>
::<math>\begin{align}
  & {{R}_{U}}(T)= & {{e}^{-\tfrac{T}{{{m}_{U}}}}} \\
& {{R}_{L}}(T)= & {{e}^{-\tfrac{T}{{{m}_{L}}}}} 
\end{align}</math>
 
<br>
where  <math>{{m}_{U}}</math>  and  <math>{{m}_{L}}</math>  are estimated estimated by:
 
<br>
::<math>\begin{align}
& {{m}_{U}}= \widehat{m}\cdot {{e}^{\tfrac{{{K}_{\alpha }}\sqrt{Var(\widehat{m})}}{\widehat{m}}}} \\
& {{m}_{L}}= \widehat{m}\cdot {{e}^{-\tfrac{{{K}_{\alpha }}\sqrt{Var(\widehat{m})}}{\widehat{m}}}} 
\end{align}</math>
