Web5 de feb. de 2011 · then . The Radon-Nikodym theorem deals with this. Essentially it says that we has a density with respect to . For instance many people know the p.d.f. of a Gaussian distribution but the reason that the p.d.f. exists in because the Gaussian measure is absolutely continuous with respect to the Lebesgue measure. Corollary: An important application is in probability theory, leading to the probability density function of a random variable .
