Erlang Distribution

Erlang Statistical Distribution


General Characteristics

  • The Erlang distribution is, like its ‘parent’ distribution, a two-parameter family of continuous probability distributions.
  • It is a special case of Gamma distribution.



Specific Characteristics

Key Measures:

Mean, k


Range of values:

0 < x < ∞



Mean = k


Standard Deviation, SD:

SD = (Mean) / √[k]



Erlang distributions can be used; to calculate the time between failures, in telephone engineering to examine the number of calls that might be made simultaneously to call centers operators & in queuing theory.
