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

An alpha continuous random variable.

%(before_notes)s

The probability density function for alpha (^[1], ^[2]) is:

f (x, a) = \frac{1}{x ^{2} Φ ( a ) 2 π} * exp (- \frac{1}{2} (a - 1/ x)^{2})

where $Φ$ is the normal CDF, $x > 0$ , and $a > 0$ .

alpha takes a as a shape parameter.
