WebMar 24, 2024 · The norm of a complex number, 2-norm of a vector, or 2-norm of a (numeric) matrix is returned by Norm[expr]. Furthermore, the generalized -norm of a vector or (numeric) matrix is returned by Norm[expr, p]. The norm (length) of a vector should not be confused with a normal vector (a vector perpendicular to a surface). WebMultivariate Normal Deﬁnition: A random vector X2Rd is multinormal if for each v2Rd the random variable hX;viis univariate normal. Note: A constant c2R is regarded as N(c;0) Fact: If X= (X 1;:::;X d)t is multinormal then components X 1;:::;X d are univariate normal. In particular, E(X) and Var(X) are well deﬁned. Note: Converse is not true.

WebNorms are important as they link the vector interpretation of the stream with statistical properties of the data. We can interpret the vector x as the empirical distribution of the data in the stream, and then ‖ x ‖ 2 corresponds to the second-order moment of x , closely related to its variance, that is, a measure of dispersion of x . Web7.2 Matrix Norms. We used vector norms to measure the length of a vector, and we will develop matrix norms to measure the size of a matrix.
