CalculateAcc.m

function [TP, TN, FN, FP] = CalculateAcc(ytest, yhat, theta, upper, lower)
    % This function calculates the accuracy of the test set based on 
    % the thresholds provided
    % Parameters:
    % ytest: the test set vector
    % yhat: the raw test set predictions
    % theta: the threshold for classification
    % upper: the positive value of the test set
    % lower: the negative value of the test set
    TP = sum(and(ytest==upper, yhat >= theta));
    FP = sum(and(ytest==lower, yhat >= theta));
    TN = sum(and(ytest==lower, yhat < theta));
    FN = sum(and(ytest==upper, yhat < theta));
