class powernorm_gen(momtype = 1, a = None, b = None, xtol = 1e-14, badvalue = None, name = None, longname = None, shapes = None, seed = None)

A power normal continuous random variable.

%(before_notes)s

The probability density function for powernorm is:

f (x, c) = c ϕ (x) (Φ (- x))^{c - 1}

where $ϕ$ is the normal pdf, $Φ$ is the normal cdf, $x$ is any real, and $c > 0$ ^[1].

powernorm takes c as a shape parameter for $c$ .
