==The Logistic Reliability Function==
#REDIRECT [[The_Logistic_Distribution]]
The reliability for a mission of time  <math>T</math> , starting at age 0, for the logistic distribution is determined by:
 
::<math>R(T)=\int_{T}^{\infty }f(t)dt</math>
 
:or:
 
::<math>R(T)=\frac{1}{1+{{e}^{z}}}</math>
 
The unreliability function is:
 
::<math>F=\frac{{{e}^{z}}}{1+{{e}^{z}}}</math>
 
:where:
 
::<math>z=\frac{T-\mu }{\sigma }</math>
