WebWhen the equation is solved, the parameter values which minimizes the cost function is given by the following well-known formula: β = ( X T X) − 1 X T Y where β is the parameter values, X is the design matrix, and Y is the response vector. Note that to have a solution X T X must be invertible. WebAll the orthogonal matrices are invertible. Since the transpose holds back the determinant, therefore we can say, the determinant of an orthogonal matrix is always equal to the -1 or +1. All orthogonal matrices are square matrices but not all square matrices are orthogonal. Orthogonal Matrix Properties
