1. A method for evaluating a calibration of an analyte sensor, the method comprising:

  • receiving sensor data from an analyte sensor, during a time period of continuous analyte sensing of a host, including one or more sensor data points;

    receiving reference data, during the time period of continuous analyte sensing of the host, including one or more reference data points;

    providing one or more matched data pairs by matching a reference data point to a substantially time corresponding sensor data point;

    forming a calibration set including the one or more matched data pairs;

    evaluating, during the time period of continuous analyte sensing of the host, a clinical acceptability of the one or more matched data pairs, wherein the clinical acceptability is based at least in part on a clinical error grid analysis; and

    processing the sensor data in response to the clinical acceptability of the one or more matched data pairs meeting a criterion.
