Actual Error Covariance

Famous quotes containing the words actual and/or error:

    There is something else which has the power to awaken us to the truth. It is the works of writers of genius.... They give us, in the guise of fiction, something equivalent to the actual density of the real, that density which life offers us every day but which we are unable to grasp because we are amusing ourselves with lies.
    Simone Weil (1909–1943)

    The next work of Carlyle will be entitled “Bow-Wow,” and the title-page will have a motto from the opening chapter of the Koran: “There is no error in this Book.”
    Edgar Allan Poe (1809–1845)
