If the random variable X has the density function fx(x)={ θ/λ(1+x/λ)-(0+1)0,x＞0,otherwise,then X is said to obey Lomax distribution,where λ＞0 is the scale parameter and θ＞0 is the shape parameter.It is proved that,as θ → ∞,Lomax distribution is uniformly asymptotic exponential distribution Exp(θ-1/λ).
