1. A method for monitoring an analyte using an analyte monitoring system including a data processing device and a drug delivery device, comprising:

  • monitoring, using the data processing device of the analyte monitoring system, a data stream including a set of contiguous source data points related to a concentration of the analyte;

    providing, using the data processing device of the analyte monitoring system, one or more sets of maximum lag corrected signals from the set of contiguous source data points;

    providing, using the data processing device of the analyte monitoring system, a first one or more sets of maximum smoothed signals from the set of contiguous source data points, wherein each of the first one or more sets of maximum smoothed signals is generated utilizing a first smoothing algorithm;

    providing, using the data processing device of the analyte monitoring system, a second one or more sets of maximum smoothed signals from the set of contiguous source data points, wherein each of the second one or more sets of maximum smoothed signals is generated utilizing a second smoothing algorithm;

    determining, using the data processing device of the analyte monitoring system, the analyte concentration utilizing a weighted combination of the one or more sets of maximum lag corrected signals and the first and second one or more sets of maximum smoothed signals, wherein more weight is placed on the one or more sets of maximum lag corrected signals to determine the analyte concentration;

    determining, using the data processing device of the analyte monitoring system, a rate of change in the analyte concentration utilizing a weighted combination of the one or more sets of maximum lag corrected signals and the first and second one or more sets of maximum smoothed signals, wherein more weight is placed on the first and second one or more sets of maximum smoothed signals to determine the rate of change; and

    delivering, using the drug delivery device of the analyte monitoring system, a drug based on the determined analyte concentration.
