Exercise  Design a data set with predefined correlations
The goal of this exercise is to get acquainted with the correlation coefficient. Try to design an artificial data set containing 20 "measurements" on 4 variables (v_{1}..v_{4}). The variables v_{2} to v_{4} should be correlated to variable v_{1}, showing the following approximate (+/ 0.1) correlation coefficients r_{i,j}: r_{1,2} = 0.0
