Various methods of accelerometer calibration can be used to increase the precision of acceleration measurements. The methods tested are two 12-parameter linear least squares optimizations, one using four calibration orientations, one using eight orientations, and two 15-parameter least squares optimizations using eight and 19 calibration orientations. Based on the data gathered, while it is not necessary to change the calibration method currently in use, good results could be obtained from applying a 12-parameter, 8-orientation least squares calibration without significant increase in time required for calibration.. : A British biometrician, Sir Francis Galton, defined regression as ‘stepping back towards the average’. He found that the offspring of abnormally tall or short parents tends to regress or step back to average.. Regression Trees.
