Systems and methods for dynamically and intelligently estimating analyte data from a continuous analyte sensor, including receiving a data stream, selecting one of a plurality of algorithms, and employing the selected algorithm to estimate analyte values. Additional data processing includes evaluating the selected estimative algorithms, analyzing a variation of the estimated analyte values based on statistical, clinical, or physiological parameters, comparing the estimated analyte values with corresponding measure analyte values, and providing output to a user. Estimation can be used to compensate for time lag, match sensor data with corresponding reference data, warn of upcoming clinical risk, replace erroneous sensor data signals, and provide more timely analyte information encourage proactive behavior and preempt clinical risk.

1. A method for estimating an analyte value from a continuous analyte sensor, the method comprising: receiving a data stream from a continuous analyte sensor for a time period;evaluating, using a processor module, the data stream;estimating, using the processor module, at least one analyte value for a future time period based on the data stream evaluation,determining, using the processor module, a confidence level in an accuracy of the estimated at least one analyte value; andtriggering, using the processor module, an alarm when the estimated analyte value meets a first criterion and the confidence level meets a second criterion. 2. The method of claim 1, wherein evaluating the data stream comprises evaluating a rate of change. 3. The method of claim 1, wherein evaluating the data stream comprises performing a first derivative analysis or a second derivative analysis. 4. The method of claim 1, wherein evaluating the data stream comprises determining the confidence level. 5. A system for estimating an analyte value from a continuous analyte sensor, comprising: a sensor data receiving module configured to receive a data stream from a continuous analyte sensor for a time period; anda processor module configured to evaluate the data stream, estimate at least one analyte value for a future time period based on the data stream evaluation, determine a confidence level in an accurac of the estimated at least one anal e value and trigger an alarm when the estimated analyte value meets a first criterion and the confidence level meets a second criterion. 6. The system of claim 5, wherein the processor module is configured to evaluate the data stream by determining a rate of change of the data stream. 7. The system of claim 5, wherein the processor module is configured to evaluate the data stream by performing a first derivative analysis or a second derivative analysis. 8. The system of claim 5, wherein the processor module is configured to determine the confidence level based on the evaluation of the data stream.
