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

A folded normal continuous random variable.

%(before_notes)s

The probability density function for foldnorm is:

f (x, c) = 2/ π cos h (c x) exp (- \frac{x ^{2} + c ^{2}}{2})

for $x \geq 0$ and $c \geq 0$ .

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