.... Now that we have established how our framework can be used to generate many different estimates of migration from the same set of digital trace data, the question becomes how to evaluate the output. Our strategy is to analyze migration estimates in a manner equivalent to that of a survival function...

We can address this issue by smoothing the distribution of ρ t ' s to yield monotonically decreasing S ( t ) estimates. We suggest smoothing the ρ t values by fitting a polynomial function. One could also...
