Notes

The probability density function for mielke is:

f (x, k, s) = \frac{k x ^{k - 1}}{( 1 + x ^{s} ) ^{1 + k / s}}

for $x > 0$ and $k, s > 0$ . The distribution is sometimes called Dagum distribution (^[2]). It was already defined in ^[3], called a Burr Type III distribution (burr with parameters c=s and d=k/s).

mielke takes k and s as shape parameters.
