Figure 2

Data were generated based on parameters ’s following Gaussian distribution with different parameters for the within- and between-cluster relations, , , , and . The estimated versus the original parameters ’s are shown for (), where (), (), (), (), (), (), (), (), and (), respectively. MSE = 1.12556.
