The Gamma Mean, Median and Mode
The gamma mean or MTTF is:
- [math]\displaystyle{ \overline{T}=k{{e}^{\mu }} }[/math]
The mode exists if [math]\displaystyle{ k\gt 1 }[/math] and is given by:
- [math]\displaystyle{ \tilde{T}=(k-1){{e}^{\mu }} }[/math]
The median is:
- [math]\displaystyle{ \widehat{T}={{e}^{\mu +\ln (\Gamma _{I}^{-1}(0.5;k))}} }[/math]
