dataset = john begin description This data set comes from John, J.A. (1978), "Outliers in Factorial Experiments," Applied Statistics, 27, 111-119. Case 11 with y=14 is an outlier that draws various numerical transformation methods from lambda = 1. The data is a 3^(4-1) experiment. Factor A = draw ratio B = relax ratio C = draw roll temp D = hot plate temp The response y is a scaled tensile property of the produced industrial nylon yarn. end description begin variables Col 0 = Obs Col 1 = AL Col 2 = AQ Col 3 = BL Col 4 = BQ Col 5 = CL Col 6 = CQ Col 7 = DL Col 8 = DQ Col 9 = y Col 10 = resids end variables begin data 1 -1 1 -1 1 -1 1 -1 1 43 2.3889 2 0 -2 -1 1 -1 1 0 -2 56 -0.3333 3 1 1 -1 1 -1 1 1 1 68 8.7222 4 -1 1 0 -2 -1 1 1 1 18 -13.4722 5 0 -2 0 -2 -1 1 -1 1 50 7.6667 6 1 1 0 -2 -1 1 0 -2 43 -6.7500 7 -1 1 1 1 -1 1 0 -2 26 -0.8889 8 0 -2 1 1 -1 1 1 1 42 1.1111 9 1 1 1 1 -1 1 -1 1 45 1.5556 10 -1 1 -1 1 0 -2 1 1 54 15.6389 11 0 -2 -1 1 0 -2 -1 1 14 -32.2222 12 1 1 -1 1 0 -2 0 -2 57 6.3611 13 -1 1 0 -2 0 -2 0 -2 37 4.0000 14 0 -2 0 -2 0 -2 1 1 50 6.0000 15 1 1 0 -2 0 -2 -1 1 36 -7.5556 16 -1 1 1 1 0 -2 -1 1 40 9.1389 17 0 -2 1 1 0 -2 0 -2 46 -0.3333 18 1 1 1 1 0 -2 1 1 48 -1.0278 19 -1 1 -1 1 1 1 0 -2 26 -4.0000 20 0 -2 -1 1 1 1 1 1 38 0.0000 21 1 1 -1 1 1 1 -1 1 38 3.4444 22 -1 1 0 -2 1 1 -1 1 31 3.9167 23 0 -2 0 -2 1 1 0 -2 46 6.4444 24 1 1 0 -2 1 1 1 1 39 -0.2500 25 -1 1 1 1 1 1 1 1 20 -16.7222 26 0 -2 1 1 1 1 -1 1 56 11.6667 27 1 1 1 1 1 1 0 -2 44 -4.5000
