Gamma Statistical Distribution
- The Gamma distribution is a two-parameter family of continuous probability distributions.
- Some statistical distributions are special cases of Gamma distribution including; Erlang distribution, Exponential distribution and Chi-Squared distribution.
Shape & Scale
Range of values:
0 < x < ∞
Mean = Shape * Scale
Standard Deviation, SD:
SD = √[Shape * Scale]
Gamma distributions can be used; to calculate the time required to complete a task & also to calculate inter-arrival time, as well as time taken between failures.
