One of two multivariate regression data sets from paper industry, from an experiment at the paper plant Norske Skog, Skogn, Norway. They have been described and analysed in:
Aldrin, M. (1996), "Moderate projection pursuit regression for multivariate response data", Computational Statistics and Data Analysis,
21, p. 501-531.
It consists of 30 observations (rows) and 22 variables (columns), but all response variables are missing for the 28th observation. Columns 1 to 13 are response variables that describes various qualities of the paper. Columns 14 to 22 are 9 predictor variables. The first three predictor variables (x1 in column 14, x2 in column 15 and x3 in column 16) were varied systematically through the experiment, taking the values 1, 0 and -1. The next three predictor variables (columns 17 to 19) are constructed as x1**2, x2**2 and x3**2. The last three predictor variables (columns 20 to 22) are constructed as x1*x2, x1*x3 and x2*x3.
