identity.deriv2(p)

Second derivative of the power transform

Parameters:

Parameters:	p : array-like Mean parameters
Returns:	g’‘(p) : array Second derivative of the power transform of `p`

p : array-like

Mean parameters

Returns:

g’‘(p) : array

Second derivative of the power transform of p

g’‘(p) = power * (power - 1) * p`**(`power - 2)
