摘要

On method the authors use to predict facility oper- ating costs is a statistical regression of historical costs against time. The costs considered are either utility costs or maintenance and repair costs. Clearly, what the au- thors are attempting to estimate is the cost of operating and maintaining a facility in good working condition. However, the estimated slope coefficient is based on ac- Counting data and represents the average rate of change, The trendline, of actual spending over time.
