The Equivariance Principle duration 24 minutes 41 seconds The Equivariance Principle The Equivariance Principle	The Equivariance Principle The previous two lessons both describe data reduction principles in the following way. A function T(x) of the sample is specified, and the principle states that if x and y are two sample points with… equivariance principle measurement invariance formal invariance group of functions invariant family transformations From Jane Harvill 181 plays 0
Bivariate Transformations duration 19 minutes 24 seconds Bivariate Transformations Bivariate Transformations	Bivariate Transformations Earlier methods of finding distributions of a function of a random variable were discussed. In this lesson, we learn how to extend these ideas to the case of bivariate vectors. Specifically, if (X,… bivariate transformations discrete random vector continuous random vector From Jane Harvill 296 plays 0
