Gamma Distribution

Gamma Statistical Distribution

 

General Characteristics

  • 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.

 

 

Specific Characteristics

Key Measures:

Shape & Scale

 

Range of values:

0 < x < ∞

 

Mean:

Mean = Shape * Scale

 

Standard Deviation, SD:

SD = √[Shape * Scale]

 

Application

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.
