The purpose of this thesis is to derive and compare asymptotic
performances of certain tests of independence, interchangeability
and equality of the distributions of_ratios Y/X for positive variates
and Y with joint c.d.f. H(x,y) of particular forms. Three bivariate
families, Morgenstern, Plackett, and Moran, are considered which permit
marginal c.d.f.'s...
