Heart rate data (Oximeter PPG vs Kalman PPGI) for eighteen patient used for statistical analysis

In the first attached data, 'Subject' is the person identificator, 'Measurement_Number' is the sample number of total measurement, 'Measurement_Number_Subject' is the sample number per person, 'HR_Fingertip_Pulse_Oximeter' is the heart rate measured by the fingertip pulse oximeter method, and 'HR_PPGI_Kalman' is the heart rate measured by the PPGI Kalman method. Also, 'Subject' is a number assigned to classify eighteen patients. Each sample is the number of heart rate calculated over a 6 s sliding-windows size.<br>In the second attached data, 'Number' is the sample number of total measurement, 'ICA_CPU_Usage' is the CPU usage measured when PPGI ICA method estimated heart rate, and 'Kalman_CPU_Usage' s the CPU usage measured when PPGI Kalman method estimated heart rate.
