Abstract:
A method for ascertaining a relationship between at least one factor and a corresponding physical results for use in estimating the result from at least one sensed factor value, the method comprising:measuring a selected physical result to obtain result values;sensing at least one factor of the physical result to produce at lease one sensed factor value;ascertaining a first function based upon said at least one sensed factor value and the corresponding measured physical result values, wherein the first function estimates the physical result based upon sensed factor values;segmenting possible physical result values into a plurality of subsets;ascertaining a second function for each subset based upon sensed factor values and corresponding measured physical result values within each corresponding subset, wherein each second function estimates the physical result based on sensed factor values; andascertaining the relationship between said least one factor and the corresponding physical result based upon the first function and the second function.
