Actual Error Covariance

Famous quotes containing the words actual and/or error:

“What a perpetual disappointment is actual society, even of the virtuous and gifted! After interviews have been compassed with long foresight, we must be tormented presently by baffled blows, by sudden, unseasonable apathies, by epilepsies of wit and of animal spirits, in the heyday of friendship and thought. Our faculties do not play us true, and both parties are relieved by solitude.”
—Ralph Waldo Emerson (1803–1882)

“Children, then, acquire social skills not so much from adults as from their interactions with one another. They are likely to discover through trial and error which strategies work and which do not, and later to reflect consciously on what they have learned.”
—Zick Rubin (20th century)
