Actual Error Covariance

Famous quotes containing the words actual and/or error:

    Happy is the novelist who manages to preserve an actual love letter that he received when he was young within a work of fiction, embedded in it like a clean bullet in flabby flesh and quite secure there, among spurious lives.
    Vladimir Nabokov (1899–1977)

    We call contrary to nature what happens contrary to custom; nothing is anything but according to nature, whatever it may be, Let this universal and natural reason drive out of us the error and astonishment that novelty brings us.
    Michel de Montaigne (1533–1592)
