KJ 7.2 Friedman (1991) introduced several benchmark data sets create by simulation. One of these simulations used the following nonlinear equation to create data: \(y\ =\ 10sin(πx_1x_2)\ +\ 20(x_3\ −\ 0.5)^2\ +\ 10x_4\ +\ 5x_5\ +\ N(0,\ σ^2)\) where the x values are random variables uniformly distributed between [0, 1] (there are also 5 oth...

KJ 6.3 A chemical manufacturing process for a pharmaceutical product was discussed in Sect. 1.4. In this problem, the objective is to understand the relationship between biological measurements of the raw materials (predictors), measurements of the manufacturing process (predictors), and the response of the product yield. Biological predictors...

KJ 3.1 KJ 3.1 (a) The UC Irvine Machine Learning Repository contains a data set related to glass identification. The data consist of 214 glass samples labeled as one of seven class categories. There are nine predictors, including the refrative index and percentages of eight elements: Na, Mg, Al, Si, K, Ca, Ba, and Fe. Using visualizations, exp...
