First Claim
1. A method for determining an analyte concentration in a sample, comprising:
- generating an output signal responsive to a concentration of an analyte in a sample and an input signal;
determining a compensated output signal from the output signal in response to a primary function and a first residual function; and
determining the analyte concentration in the sample from the compensated output signal.

Abstract
A biosensor system determines analyte concentration from an output signal generated from a light-identifiable species or a redox reaction of the analyte. The biosensor system compensates at least 50% of the total error in the output signal with a primary function and compensates a portion of the remaining error with a residual function. The amount of error compensation provided by the primary and residual functions may be adjusted with a weighing coefficient. The compensation method including a primary function and a residual function may be used to determine analyte concentrations having improved accuracy from output signals including components attributable to error.
