摘要：	We decided to create statistical models of the course elevation profiles of the U.S. Army's vehicle test courses at the Aberdeen Proving Grounds, Aberdeen, Maryland, and at the Yuma Test Facility, Yuma Arizona. As a first step in creating the models, we decided first to test the data, the output from various profilometer runs, to see if the course elevations met the assumptions made in the past and in current models. The assumptions are that the course elevation profiles, considered as time series (signals), are Linear, Stationary and Gaussian. Because of past analyses we had suspected that these assumptions were not met. In the body of the text we attempt to explain the statistical terminology and how the statistics are used. The appendices are reserved for the technicalities of the tests.
