Statistical Models of Sewage Waste Generation Rates Aboard the USS HAROLD J. ELLISON (DD 864).

Abstract

Aft Head sewage waste generation data collected at 15-minute intervals onboard the USS HAROLD J. ELLISON, (DD864) both in port and at sea, are analyzed by Box-Jenkins time series analysis techniques. Results show that both in-port and at-sea data may be modeled by pure autoregressive Gaussian Processes with dependence order three for in-port data and order one for at-sea data. Maximum likelihood parameter estimates are provided and model fit checks are performed. A method is provided to extrapolate model results to other U.S. ships. (Author)
