Claim 9:
10. A system for lag correction of sensor data from a glucose sensor, comprising:
a processor; and
a memory coupled to the processor, the memory storing processor executable instructions to:
receive sensor data from the glucose sensor, the sensor data including historical glucose sensor data over a plurality of intervals;
determine a variability of the historical glucose sensor data over each of the plurality of intervals;
compare the variability of the historical glucose sensor data of a recent interval of the plurality of intervals to at least one prior variability determined from prior intervals of the plurality of intervals;
calculate a noise metric of the historical glucose sensor data of the recent interval of the plurality of intervals;
set an amount of lag correction based on the noise metric and at least one of the variability of the recent interval and the at least one prior variability; and
compute lag corrected values based on the amount of lag correction.
