Abstract

A user device (e.g., a mobile device) receives testing period data during a testing period. The user device determines that a portion of the data is missing based on an analysis of the received testing period data. The analysis of the received data includes an analysis of one or more blood glucose levels and an analysis of the dietary intake data, the medication data, and the activity data. The user device imputes the missing portion of the data with substitute data determined using predictive learning. The user device calculates a confidence level associated with the substitute data. The user device identifies, using the substitute data, a progression or a regression in a diabetic condition associated with the user.
