Table 1.

Details on the six datasets analyzed in the article. “N egos” is the number of respondents with valid personal network data included in the analysis. ¹ The survey asked edge interpreters only for 25 randomly sampled alters out of the 45 named by ego. For all respondents, the same 25 randomly extracted numbers where used to select the alters. ² Variation in number of alters per ego in the [10, 25] range was simulated by extracting random integers with preassigned probabilities (see appendix). ³ Variation in number of alters per ego in the [5, 20] range was simulated by extracting random integers with preassigned probabilities (see appendix). ⁴ See appendix for details on the name generators. ⁵ See appendix for details on the selection of alters for tie questions.
