WebDerivatives with respect to vectors Let x ∈ Rn (a column vector) and let f : Rn → R. The derivative of f with respect to x is the row vector: ∂f ∂x = (∂f ∂x1,..., ∂f ∂xn) ∂f ∂x is called the gradient of f. The Hessian matrix is the square matrix of second partial derivatives of a scalar valued function f: H(f) = ∂2f ∂x2 ... WebFrom time to time, I come across with derivation operations which are executed with regard to a vector. For example, the least squares estimation method with more than one explanatory variables is written like: y i = β 1 + β 2 x 2 i +... + β k x k i + ϵ i. And then it is: y = X b + e. Where y is the Nx1 column vector of target variables, X ...
