Sensitivity analysis for k 1 and k 2 in the training database. Constant k 1 is represented along the x-axis. Curves (in shades of gray) are shown for k 2 . Higher values of k 1 increased P (in dot lines) but decreased S (in solid lines). Acc (dash lines) remained almost constant for different values of k 1 and k 2 . Optimal values for k 1 were found as a compromise between S and SP and the obtained ranges are highlighted in gray-shadowed areas. Performance indexes corresponding to the selected k 2 =0.2 are shown in squares.
