1. A method for evaluating a quality of 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 a plurality of matched data pairs;

    evaluating a quality of the calibration set, during the time period of continuous analyte sensing of the host, based on a statistical association of the calibration set and a clinical association of the one or more matched data pairs, wherein the statistical association comprises a statistical analysis of the plurality of matched data pairs'"'"' correlation to or deviation from a curve;

    modifying the calibration set in response to the statistical association not meeting a criterion or the clinical association not meeting a criterion; and

    processing the sensor data in response to the statistical association meeting a criterion and the clinical association meeting a criterion.
