Using ALTA and the T-NT lognormal model, the following parameters were obtained:
 
<br>
::<math>\begin{align}
  \widehat{Std}=\ & 0.182558 \\
  \widehat{B}=\ & 3729.650303 \\
  \widehat{C}=\ & 0.035292 \\
  \widehat{n}=\ & 0.776797 
\end{align}</math>

An acceleration factor plot, in which one of the stresses must be kept constant, can also be obtained. For example, in the following plot, the acceleration factor is plotted versus temperature given a constant voltage of 2V, as shown next.
