Argus distribution.

%(before_notes)s

The probability density function for argus is:

f (x, χ) = \frac{χ ^{3}}{2 π Ψ ( χ )} x 1 - x^{2} exp (- χ^{2} (1 - x^{2}) /2)

for $0 < x < 1$ and $χ > 0$ , where

Ψ (χ) = Φ (χ) - χ ϕ (χ) - 1/2

with $Φ$ and $ϕ$ being the CDF and PDF of a standard normal distribution, respectively.

argus takes $χ$ as shape a parameter. Details about sampling from the ARGUS distribution can be found in ^[2].
