A package that transform intermediate log files into features of interest for analysis

Project description

Introduction


This repository include Python scripts that transform raw sensor data collected from Android mobile devices into features of interest for analysis.

Current research topic: identify contextual prompt-level factors that predict response or no response in microEMA.

Statistical methodology: multi-level modeling

Outcomes: compliance rate

Predictors:

  • Within-person or prompt level:

    • time of the day
    • day of the week
    • day in study
    • activity level
    • battery level
    • location
  • Between-person or person level

    • age
    • gender
    • study mode

Code Usage for Feature Matrix Generation


  1. This project has been wrapped up as a Pypi package. Use pip to install.
  2. Clone this project and run locally.
#!python
python main_ema.py [intermediate_participant_path] [output_dir_path] [date_in_study] [decryption_password]

e.g., python main_ema.py G:...\intermediate_file\participant_id C:...\output_folder 2021-01-01 password

Special Notice

  • Delete misc folder before running code, if new participants' intermediate folder has been created.
