1. A method comprising:
- obtaining samples of an electrical signal generated by a sensor, said samples having sample values associated with measurements of a blood-glucose concentration;
individually weighting at least some of said sample values according to a function of blood glucose reference samples associated with said sample values; and
estimating a relationship of sample values with said blood-glucose concentration based, at least in part, on said individually weighted samples.

Abstract
The subject matter disclosed herein relates to systems, methods and/or devices for calibrating sensor data to be used in estimating a blood glucose concentration. A relationship between sensor measurements and reference readings may be used to estimate a relationship between sensor measurements and blood glucose concentration. Such sensor measurements may be weighted according to a decreasing function of uncertainty associated with sensor values.
