摘要
Methods and apparatus are provided for adaptively detecting trend changes in data. An initial set of data points is collected and a curve fit thereof is computed. A set of new data points is collected, and whether or not a trend change has occurred is detected. If a trend change has not occurred, the set of new data points is made part of the initial set of data points, and the steps of computing a curve fit, collecting new data points, and detecting whether or not a trend change has occurred are repeated. If, however, a trend change has occurred, a determination is made as to where the trend change was initiated, a curve fit for all data collected from where the detected trend change was initiated is computed, and the steps of collecting new data points and detecting whether or not a trend change has occurred are repeated.
