Class InverseLinearWeight

  • All Implemented Interfaces:

    public final class InverseLinearWeight
    extends java.lang.Object
    implements WeightFunction
    Inverse linear weight function using \(.1+0.9\frac{\text{distance}}{\max}\).

    This weight is not particularly reasonable. Instead it serves the purpose of testing the effects of a badly chosen weight function.

    This function has increasing weight, from 0.1 to 1.0 when the distance equals the maximum.

        NOTE: increasing weights are non-standard, and mostly for testing

        Specified by:
        getWeight in interface WeightFunction
        distance - distance of the query point
        max - maximum distance of all included points
        stddev - standard deviation (i.e. quadratic mean / RMS) of the included points
        weight for the query point
