Tīmeklis18.4. The Radon-Nikodym Theorem 1 Section 18.4. The Radon-Nikodym Theorem Note. For (X,M,µ) a measure space and f a nonnegative function on X that is measurable with respect to M, the set function ν on M defined as ν(E) = Z E f dµ is a measure on (X,M). This follows from the fact that ν(∅) = R ∅ f dµ = 0 and ν http://www.stat.yale.edu/~pollard/Manuscripts+Notes/Beijing2010/UGMTP_chap3%5bpart%5d.pdf

The Radon-Nikodym derivative f for a measurable space ( X, F) and measures μ, ν where ν 's support contains μ 's support, is defined as follows: … TīmeklisThe Radon-nikodym derivative: a practical example. We are now going to explain a simple concept that is usually made more difficult than necessary, the Radon-Nikodym derivative. First of all let’s clarify the idea of probability space. Imagine a coin tossing with two possible outcomes, Head and Tail.

The density dν/ µ is often called the Radon-Nikodym derivative ofν with respect to µ, a reference to the result described in Theorem <4> below. The word derivative suggests a limit of a ratio of ν and µ measures of “small”sets. For µ equal to Lebesgue measure on a Euclidean space, dν/dµ can …
