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.
