         2 . A method for calibrating sensor data generated by a continuous analyte sensor, comprising:
 generating sensor data using a continuous analyte sensor;   iteratively determining, with an electronic device, a sensitivity value of the continuous analyte sensor by applying a priori information comprising a sensitivity profile, wherein the sensitivity profile is a function of time, wherein the sensitivity profile comprises an initial sensitivity value associated with a correlation between a sensitivity determined from in vitro analyte concentration measurements and a sensitivity determined from in vivo analyte concentration measurements; and   calibrating the sensor data based at least in part on the determined sensitivity value.   
     
     
         3 . The method of  claim 2 , wherein the a priori information is associated with a calibration code. 
     
     
         4 . The method of  claim 2 , wherein the a priori sensitivity information is stored in the sensor electronics prior to use of the sensor. 
     
     
         5 . The method of  claim 2 , wherein calibrating the sensor data is performed iteratively throughout a substantially entire sensor session. 
     
     
         6 . The method of  claim 2 , wherein iteratively determining a sensitivity value is performed at regular intervals or performed at irregular intervals, as determined by the a priori information. 
     
     
         7 . The method of  claim 2 , wherein iteratively determining a sensitivity value is performed throughout a substantially entire sensor session. 
     
     
         8 . The method of  claim 2 , wherein determining a sensitivity value is performed in substantially real time. 
     
     
         9 . The method of  claim 2 , wherein the sensitivity value of the continuous analyte sensor is also a function of a second parameter that is not time. 
     
     
         10 . The method of  claim 9 , wherein the third parameter is selected from the group consisting of: temperature or an analyte concentration of a fluid surrounding the continuous analyte sensor during startup of the sensor, and combinations thereof. 
     
     
         11 . The method of  claim 2 , wherein calibrating the sensor data is performed without using reference blood glucose data. 
     
     
         12 . The method of  claim 2 , further comprising receiving at least one calibration code, wherein the calibration code is associated with the sensitivity profile; and
 applying the at least one calibration code to the electronic device at a predetermined time after start of the sensor session.   
     
     
         13 . The method of  claim 2 , wherein the sensitivity profile is a function of a parameter associated with fabrication of the sensor.
