The  <math>pdf</math>  of the lognormal distribution is given by:
<br>
<math>f(T)=\frac{1}{T\text{ }{{\sigma }_{{{T}'}}}\sqrt{2\pi }}{{e}^{-\tfrac{1}{2}{{\left( \tfrac{{T}'-\overline{{{T}'}}}{{{\sigma }_{{{T}'}}}} \right)}^{2}}}}</math>
<br>
where:
<br>
<math>{T}'=\ln (T)</math>
<br>
<math>T=\text{times-to-failure}</math>
<br>
and:
<br>
• <math>\overline{{{T}'}}=</math> mean of the natural logarithms of the times-to-failure.
 
• <math>{{\sigma }_{{{T}'}}}=</math> standard deviation of the natural logarithms of the times-to-failure.
