function standardError = computeStandardError(jacobian, residual) % computeStandardError compute the standard error of estimated parameters % standardError = computeStandardError returns a vector containing the % standard errors of estimated parameters. jacobian is the Jacobian matrix, % and residual is a vector of residuals. R = qr(jacobian,0); n = size(jacobian,1)-size(jacobian,2); % be careful with memory clear jacobian; mse = sum(sum(residual.^2, 2)) / n; Rinv = inv(R); Sigma = Rinv*Rinv'*mse; standardError = full(sqrt(diag(Sigma))); end
