Project: Measure the Quality of CerebUnit Validation Tests

Contributions towards the project:

• Develop MockData submodule as part of CerebStats to generate mock data files for running against validation tests using a random set of values.

MockData Class contains the following methods:

Method Name	Method Type
count_files	static method
display_files	static method
clear_files	static method
generate_random_data_files	static method

• Develop TestMetrics submodule as part of CerebStats to calculate metrics such as TP, FP, TN, FN for calculation of Specificity, Sensitivity, Positive Predictive Value, and Negative Predictive Value.

TestMetrics Class contains the following methods:

Method name	Method type
calculate_metrics	instance method
get_specificity	instance method
get_sensitivity	instance method
get_npv	instance method
get_ppv	instance method
display_outcomes	instance method
display_metrics	instance method

• Add documentation for MockData Class
• Add documentation for TestMetrics Class
