Multiple Regression Analysis on Heart Rate Signal using Hand GSR and R peak of ECG signals

This paper proposes a mathematical model for the heart rate signal using hand GSR and power samples of the R peak of the ECG through multiple regression analysis. Mathematical model helps to study the relation of the dependent function with its independent functions and to correlate with the biological processes. The paper proposed four models for heart rate. Each model had R 2 values such as 0.0594, 0.2169, 0.9296 and 0.9962 respectively. The fourth model was robust and quite acceptable because of its high goodness of fit. The study also proved a non linear relationship of the heart rate signal with the hand GSR and R peak of the ECG signal.
