Claim One:
1. A method for monitoring an analyte, comprising: monitoring a data stream including a set of contiguous source data points related to the concentration of an analyte; providing one or more sets of maximum lag corrected signals from the one or more sets of monitored data stream, wherein each set of maximum lag corrected signals is generated utilizing correction terms based on time derivative estimates and historical monitored data stream, and wherein parameters for the maximum lag correction minimize the correlation between the expected glucose error and time derivative estimates and minimize the correlation between the expected glucose error and a pre-determined array of historical monitored data stream; providing one or more sets of maximum smoothing signals from the set of monitored data stream, wherein each set of maximum smoothing signals is generated utilizing a smoothing algorithm; determining analyte concentration utilizing the one or more sets of maximum lag corrected signals; and determining a rate of change in the analyte concentration utilizing the one or more sets of maximum smoothing signals.
