In statistics, a lack-of-fit test is any of many tests of a null hypothesis that a proposed statistical model fits well. See:
- Goodness of fit
- Lack-of-fit sum of squares
Famous quotes containing the word test:
“He who has never failed somewhere, that man can not be great. Failure is the true test of greatness. And if it be said, that continual success is a proof that a man wisely knows his powers,—it is only to be added, that, in that case, he knows them to be small.”
—Herman Melville (1819–1891)
