F(x) = 1 - (1 + (x/scale)^shape2)^(-shape1), x > 0.
Density, distribution function, quantile and draws by inversion of the
morie Philox uniforms (identical in the Python arm).
Usage
BurrDist(
x = NULL,
shape1 = NULL,
shape2 = NULL,
scale = 1,
p = NULL,
n = 0,
seed = 0
)
Arguments

- scale
Parameter.
- p
Probabilities for the quantile function.
- n
Number of random draws.
- seed
