Adaptive trend-change detection and function fitting system and method

A system for adaptively detecting trend changes in data, comprising:

• a data source configured to supply data points;
• and
• a processor in operable communication with the data source and configured to:
• a) collect an initial set of data points from the data source;
• b) compute a curve fit for the initial set of data points;
• c) collect new data points from the data source;
• d) determine if a trend change has occurred by processing at least a portion of the new data points to determine if the new data points differ from the computed curve fit by a predetermined metric;
• e) if a trend change has not occurred, the processor is further configured to:
• (i) make the new data points part of the initial set of data points, and
• (ii) repeat b)-d) and
• f) if a trend change has occurred, the processor is further configured to:
• (i) determine where the trend change was initiated,
• (ii) compute a curve fit for all data collected from where the trend change was initiated, and
• (iii) repeat c) and d).
