Shapley Values Calculator

Shapley Values calculator is a file that reads a json file with different criteria and calculates the shappley values.

Usage Instructions

Just run the script with the input file you want to run the script against:

$ python shapleyCalculation.py test.json

Input data

Sample input data should be a json file with two or more labeled alternatives, one or more labeled criteria, and the numeric responses to each criteria for each alternative. This example input file shows response data for 4 criteria for two different patients.

 {
"participants": [{
    "Cost": {
        "FIT:": 1.0,
        "Colonoscopy:": 0.1,
        "Flexible Sigmoidoscopy:": 0.6
    },
    "Further Testing": {
        "FIT:": 1.0,
        "Colonoscopy:": 1.0,
        "Flexible Sigmoidoscopy:": 1.0
    },
    
    "Test Preparation": {
        "FIT:": 1.0,
        "Colonoscopy:": 1.0,
        "Flexible Sigmoidoscopy:": 1.0
    },
    
    "Time": {
        "FIT:": 1.0,
        "Colonoscopy:": 1.0,
        "Flexible Sigmoidoscopy:": 1.0
    }
},
{
    "Cost": {
        "FIT:": 0.1,
        "Colonoscopy:": 1.0,
        "Flexible Sigmoidoscopy:": 1.0
    },
    
    "Further Testing": {
        "FIT:": 1.0,
        "Colonoscopy:": 1.0,
        "Flexible Sigmoidoscopy:": 1.0
    },
    
    "Test Preparation": {
        "FIT:": 1.0,
        "Colonoscopy:": 1.0,
        "Flexible Sigmoidoscopy:": 1.0
    },
    
    "Time": {
        "FIT:": 1.0,
        "Colonoscopy:": 1.0,
        "Flexible Sigmoidoscopy:": 1.0
     }
}]
}

Output data

The script will have two outputs: 1)The shell will print each of the shappley values 2)A results.txt file will be created with the shappley values of each participant plus the average of each criteria.
