Class FitCurveFunction

java.lang.Object
nz.org.riskscape.defaults.curves.FitCurveFunction
All Implemented Interfaces:
nz.org.riskscape.engine.rl.agg.AggregationFunction
public class FitCurveFunction extends Object implements nz.org.riskscape.engine.rl.agg.AggregationFunction

Aggregate function for fitting a collected set of x/y values to a curve. So far, we've only got power law, but I expect this to be extended to a range of functions, and allow options for different types of functions, e.g. try the different positively monotonic functions for loss curves, or perhaps just pick from an explicit list.

TODO add support for selecting which curves and setting the curve fitting parameters
