1. A method for processing data from an analyte sensor, comprising:

  • receiving, with an electronic device, sensor data from an analyte sensor, wherein the sensor data comprises at least one sensor data point;

    receiving reference data, wherein the reference data comprises at least one reference data point;

    matching a first reference data point to a substantially time corresponding first sensor data point to form a calibration set;

    forming a first conversion function based at least in part on the calibration set, wherein the first conversion function comprises a first baseline and a first analyte sensitivity;

    forming a second conversion function based at least in part on the calibration set, wherein the second conversion function comprises a second baseline and a second analyte sensitivity, wherein at least one attribute of the first conversion function is different from a corresponding attribute of the second conversion function, wherein the at least one attribute is selected from the group consisting of baseline, analyte sensitivity, and combinations thereof; and

    determining an analyte output value, wherein determining an analyte output value comprises applying the first conversion function to a sensor data point if the sensor data point is within a first predetermined range and applying the second conversion function to the sensor data point if the sensor data point is within a second predetermined range.
