Web$\begingroup$ Indeed. The erf might be more widely used and more general than the CDF of the Gaussian, but most students have a more intuitive sense of the Gaussian CDF ... so Mathematica's insistence on simplifying everything to erf is not only annoying, but also very confusing. $\endgroup$ – CrimsonDark WebThe error function erf is defined by erf ( x) = 2 π ∫ 0 x e − t 2 d t. Of course, it is closely related to the normal cdf Φ ( x) = P ( N < x) = 1 2 π ∫ − ∞ x e − t 2 / 2 d t (where N ∼ N ( 0, 1) is a standard normal) by the expression erf ( x) = 2 Φ ( x 2) − 1. My question is: Why is it natural or useful to define erf normalized in this way? convertir mj/kg a kj/kg
