“…That is, rather than solely analyzing self-reports of a given social network, we simulate 12 time points of sparse transfer data (in which transfers were accurately documented), and analyze these data in addition to the standard self-report data. These sparse networks of “ground-truth” data might come from field observations (e.g., “scan sampling” or “spot-checks”; Borgerhoff Mulder et al, 1985), diary methods (Paolisso & Hames, 2010), experimental games (Ross & Redhead, 2021), video recordings (DeTroy et al, 2021), GPS tracking (Davis et al, 2018), proximity detection (e.g., through cell phone data; Urban, 2021), or a variety of other methods. Even with sparse, incomplete “ground-truth” data, network reconstruction can be improved, and covariate effects on network structure and reporting parameters disambiguated.…”
