We define the hat-matrix by H = X(X^T X)^{-1}X^T. a. Show that H is a symmetric and idempotent matrix. b. Show that I - H is a symmetric and idempotent matrix. (I is the identity matrix.) Define and give an example of Quantitative variables. ...
that has ones on its diagonal and zeros everywhere else, and an inverse matrix is defined as the inverse matrix that meets the criteria of A * A sup -1 = I, where A stands for a matrix A, A sup -1 stands for the inverse of matrix A, and I stands for the identity matrix. We...
Identity Matrix Anidentity matrixis the same as the identity element in addition or multiplication. It is some matrix {eq}I {/eq} such that, for any matrix {eq}A {/eq} (of the same dimensions), the following holds: $$AI = A = IA $$ ...
