Actual Error Covariance

Famous quotes containing the words actual and/or error:

“Our ideas are the offspring of our senses; we are not more able to create the form of a being we have not seen, without retrospect to one we know, than we are able to create a new sense. He whose fancy has conceived an idea of the most beautiful form must have composed it from actual existence.”
—Henry Fuseli (1741–1825)

“We shall yet acknowledge His wisdom and our own error therein.”
—Abraham Lincoln (1809–1865)
