Stockout Probability with a Continuous
Uniform Distribution
Let us now consider two continuous distributions: the uniform and the normal distributions.
> R ] = α
Compute R such that : Prob[ D

uniform

Note that in the uniform distribution, the standard deviation is about (max - min)/3.5. In this
example, the mean is thus 100 and the standard deviation, about 30.
