ABSTRACT
Let Y be a standard exponential random variable with probability density function
f(y) = e−y, y > 0.
Define X = bY 1/c +m, b > 0, c > 0.
The distribution ofX is known as the Weibull distribution with shape parameter c, scale parameter b, and the location parameter m. Its probability density is given by
f(x|b, c,m) = c b
( x−m b
{ − [ x−m b
]c} , x > m, b > 0, c > 0.
