Figure 2From: Statistical inference for the new INAR(2) models with random coefficientThe two figures in first line are the Boxplot of estimated parameter \(\alpha _{1}, \alpha _{2}\), respectively, for Model II with \(\lambda =1\). The two figures in second line are the Boxplot of estimated parameter \(p_{1}, p_{2}\), respectively, for Model II with \(\lambda =1\). All Boxplots are obtained with sample size \(n=500\)Back to article page
