PAUL WILDER STEWART. Application of a Bivariate t Distribution to Hypothesis Testing in Crossover Designs. Under the direction of RONALD H. HELMS, Ph.D. The joint distribution of a pair of Student-t variates, (tl ,t2), is investigated and methods of computing Pr{tl £ setl and t 2 E set2} are developed. The resulting algorith~s are used to evaluate the power and actual significance level of two-...

We develop tests for predictability that are robust to both the magnitude of initial condition and degree persistence predictor.
