var_wtd_mean_cochran

This is a helper method for weighted variance computation in <code>origin_edm</code>, which is the closest to the bootstrap.

Performs network-based source estimation. Different approaches are available: effective distance median, recursive backtracking, and centrality-based source estimation. Additionally, we provide public transportation network data as well as methods for data preparation, source estimation performance analysis and visualization.
