If you look at the source code for scipy.stats.norm , you'll find that the ppf method ultimately calls scipy.special.ndtri . So to compute the inverse of the CDF of the standard no,A normal continuous random variable. The location (loc) keyword specifies the mean. ... Check accuracy of cdf and ppf: >>> >>> vals = norm.ppf([0.001, 0.5, 0.999]) >>> np.allclose([0.001, 0.5, 0.999], norm.cdf(vals)) True. Gener,scipy.stats.norm = <scipy.stats._continuous_distns.norm_gen object at 0x2b2318b8cd10>[source]¶.

The location (loc) keyword specifies the mean. The scale (scale) keyword specifies the standard deviation. As an instance of the rv_continuous class, norm object inherits from it a collection of generic methods (see be, There's one in scipy.stats: >>> import scipy.stats >>> scipy.stats.norm(0, 1) <scipy.stats.distributions.rv_frozen object at 0x928352c> >>> scipy.stats.norm(0, 1).pdf(0) 0.3989422804014327 >>> scipy.stats.nor, That is, since Python 2.7, the math library has integrated the error function math.erf(x).
