A measure is a set function that assigns a consistent magnitude to the measurable subsets of a measurable space. Examples of a measure include area and volume, where the subsets are sets of points; or the probability of an event, which is a subset of possible outcomes within a wider probability space. batang besi in englishWebJun 12, 2024 · Girsanov Theorem, Radon-Nikodym Derivative backward. 2.
