Making survey data monotonic

As one can observe in plots of the survey indices (see top here), 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 choosing the number of cohorts per run. To be more specific, we remove the observations of a cohort which are smaller than subsequent observations.

Summary

TBD.
