WebThe random variable is called the Radon Nikodym derivative of P with respect to from Geog 101 at University of Notre Dame WebRadon-Nikodym derivative and denoted by dQ=dP or dP=dQ. Clearly, for the Radon-Nikodym derivative to be well-de ned, we need to assume that nodes of the tree that are accessible under the measure Q are also accessible under the measure P. In other words: we need to avoid dividing by zero when forming the likelihood ratios.
