Example of simulated data. The example is of stand basal area of Japanese rainforest and shows scatter plots of 500 randomly selected values of the 10,000 simulated population values of the variable of interest (target variable) plotted against the corresponding auxiliary variable values when the correlation between the two variables was a 0.9 and b 0.7. The data were generated so that the straight-line relationship between the two variables for the 10,000 data values passed through the origin
