A typical Poincare plot. The horizontal axes demonstrate the illustrating the statics result at a specific epoch (x(k)) and the vertical axis illustrating the statics result after a specified epoch delay (x(k+1)). An ellipse is fitted to the data points and the Poincare plot descriptors are measured by estimating the SD perpendicular to the diametric line was defined as SD1, and the SD along the diametric line was defined as SD2 and ratio of the SD1/SD2 of the fitted ellipse.
