The J test need to take a little test by B way ,and the remaining curvlinear regression and curvplot were dealt with software of D .Therefore ,compared with test Y and Z ,the times for test J was the least .Apart from that the calulation was computer ,which decreased the workload .So ,the test J was simpler by computer . |
