Description for Figure 4.2
Plots of various estimators for population I

Figure showing six scatter plots. The graphs compare the estimations of population I total at times $t=1$ and $t=25$ for each of the following estimators: HT, MR1, MR2, MRR, MR $\left(\alpha =0.75\right)$ and MRC $\left(\alpha =0.25\right).$ For each graph, the estimation at time $t=25$ is on the y-axis (going from 900 to 1,600) and the estimation at time $t=1$ is on the x-axis (going from 800 to 1,300). The correlations $\rho$ between the point-in-time estimates at times $t=1$ and $t=25$ give a general idea of the scatter plot shapes. They are -0.014 for HT, 0.246 for RM1, 0.496 for RM2, 0.480 for RMP, 0.487 for RM and 0.009 for RMC.
