An Easy Access Interactive Statistical System For Use And Training In Biometry, Amos Addison Slaymaker Jr.

Theses and Dissertations

One of the most important tools of the applied statistician is the digital computer. It is natural, therefore, for the instructor in applied statistics to want his students to become familiar with the use of computers. If his students are going to get actual experience in using a computer for statistical analysis, he often has only two alternatives. The students can be required to write their own statistical programs or they can use programs already available through a computer facility.

Group Sequential Methods For Clinical Trials Applied To The Logistic Regression Model, Joy Duci Mele

Theses and Dissertations

The objectives of this thesis are

1. to provide a comprehensive guide to using Pocock's group sequential method for clinical trials and

2. to show by computer simulations that the group sequential method is appropriate when using the logistic regression model.

In section 1.2, clinical trials are defined with an emphasis on Phase III clinical trials. The primary intent of sections 1.2 and 1.3 is to describe clinical trial characteristics which suggest that interim analyses are desirable.
