演講題目:Notes on testing equality and interval estimation in Poisson frequency data under a three-treatment three-period crossover trial
Abstract:
When the frequency of event occurrences follows a Poisson distribution, we develop procedures for testing equality of treatments and interval estimators for the ratio of mean frequencies between treatments under a three-treatment three-period crossover design. Using Monte Carlo simula- tions, we evaluate the performance of these test procedures and interval estimators in a variety of situations. We note that all test procedures developed here can perform well with respect to Type I error even when the number of patients per group is moderate. We further note that the two weighted- least-squares (WLS) test procedures derived here are generally preferable to the other two commonly- used test procedures in t
