4. Relevant Information Paragraph:
The cases are generated using the following method:
Generate the values of 10 attributes, X1, ..., X10 independently each of
which uniformly distributed over [0,1]. Obtain the value of the target
variable Y using the equation:
Y = 10 Sin(PI.X1.X2) + 20 sqr(X3 - 0.5) + 10X4 + 5X5 + sigma(0,1)
