J.  aTests for discriminant fuctions  c1960  aIn previous paper 9Bartlet 1951, Williams 1952a, b, c; 1953, 1955) certain exact tests for discriminant functions have been discussed. These papers have also indicated how the tests may usefully be applied to a wide range of problems: the significance of discriminating function coefficients, the interpretation of interactions in factorial experiments, the concurrence of regression lines with the same independ variables and the proportionalityof regression lines with different independent variables, comparison of sets of ratios, and the testing of arbitrary scores applied to frequency data.  tS.n.t.s.d., p.243-252.
