1. A method, comprising:
- receiving one or more analyte sensor data from an analyte sensor in fluid contact with interstitial fluid under a skin layer;
receiving a reference measurement value associated with an analyte level;
determining a sensitivity parameter based on the received one or more analyte sensor data and the reference measurement value;
performing a probability analysis based on prior analyte sensor data to determine presence of signal attenuation, the probability analysis including comparing the determined sensitivity parameter to a probability distribution function that provides a likelihood of the analyte sensor with the determined sensitivity parameter in signal attenuation condition; and
generating an output value based on the probability analysis.
