1. A method for a continuous analyte monitoring system to output estimated analyte values generated using a continuous analyte sensor, the method comprising:

  • receiving sensor data from a continuous analyte sensor for a time period;

    determining in substantially real-time, using a processor module, a first level of reliability of the continuous analyte sensor based on a first portion of the sensor data, wherein the first level of reliability is selected from a plurality of predetermined levels of reliability;

    estimating, using the processor module, at least one analyte value for a first future time period based at least in part on the first portion of the sensor data;

    turning on or maintaining outputting, using the processor module, the estimated at least one analyte value for the future time period based on the determined first level of reliability;

    determining in substantially real-time, using the processor module, a second level of reliability of the continuous analyte sensor based on a second portion of the sensor data, wherein the second level of reliability is selected from the plurality of predetermined levels of reliability;

    estimating, using the processor module, at least another analyte value for a second future time period based at least in part on the second portion of the sensor data; and

    turning off outputting, using the processor module, the estimated at least another analyte value for the second future time period based on the determined second level of reliability,wherein the first level of reliability indicates a higher level of reliability than the second level of reliability.
