| As one can observe in [[admb_real:vpa_estimates|plots of the survey indices]], these are frequently not monotonic. For this reason we make the survey indices nonicreasing by removing the offending indides, and repeat the experiments in the section about [[admb_real:two_qs_cohorts_per_run|choosing the number of cohorts per run]]. To be more specific, we remove the observations of a cohort which are smaller than subsequent observations. | As one can observe in plots of the survey indices [[admb_real:sdreport_and_vpa|(see top here)]], these are frequently not monotonic.
