Data for: Partial Constrained Least Squares (PCLS) and Its Application in Soft Sensor

In those datasets, (X1,yy1), (X2,yy2), (X3,yy3) and (X4,yy4) are SIM1, SIM2, SIM3 and SIM4, respectively. In each dataset, X and yy are easy and hard to measure variables, respectively.在上述数据集中，(X₁, yy₁)、(X₂, yy₂)、(X₃, yy₃)与(X₄, yy₄)分别对应SIM1、SIM2、SIM3及SIM4。在每个数据集内，X与yy分别为易于测量的变量与难以测量的变量。
