- Least squares with known covariance.

LSCOV Least squares with known covariance. X = LSCOV(A,B,V) returns the vector X that solves A*X = B + E where E is normally distributed with zero mean and covariance V. A must be M-by-N where M > N. This is the over-determined least squares problem with covariance V of the data. The solution is found without inverting V. The vector X minimizes (A*X-B)'*inv(V)*(A*X-B). The classical linear algebra solution to this problem is: X = inv(A'*inv(V)*A)*A'*inv(V)*B [X, DX] = LSCOV(A,B,V) returns the standard errors of X in DX. The standard statistical formula for the standard error of the coefficients is: mse = B'*(inv(V) - inv(V)*A*inv(A'*inv(V)*A)*A'*inv(V))*B./(m-n) dx = sqrt(diag(inv(A'*inv(V)*A)*mse)) See also SLASH, LSQNONNEG, QR.
