• Characteristics (shape, limitations)

  • Defined for non-negative random variables
  • Positively skewed

• Parameter

  • One parameter distribution, p1 but can employ an offset to make a 2 parameter distribution
  • p1 = 1 / E[X]
  • Constant Coefficient of variation, Cv = 1
  • Constant coefficient of skewness, Cs = 2
