XIV.—Further Investigations in Factor Estimation
D. N. Lawley · Proceedings of the Royal Society of Edinburgh Section A Mathematical and Physical Sciences · 1942
Summary 7. A method of factor estimation is given in which assumptions are made only about the form of the error distributions of the tests administered. This is compared with a method previously suggested in which, on the contrary, the test scores and the individual factor measurements were assumed to be normally distributed over the population of individuals tested. A comparison is also made with other processes at present in use.
