Negative Exponential Distribution

Negative Exponential Statistical Distribution


General Characteristics

  • The Negative Exponential distribution has an inverted curve from the y-axis to the x-axis.
  • Unlike Gamma distribution which involves two parameters, the Negative Exponential distribution involves only one parameter, and is thus easier to handle compared to the aforementioned.



Specific Characteristics

Key Measures:



Range of values:

0 < x < ∞



Mean = mean


Standard Deviation, SD:

SD = mean



Negative Exponential distributions are used in a wide variety of operations, including but not limited to; calculating the time required to complete a certain task, calculating inter-arrival time & calculating the time between failures.
