All models are survey-adjusted, and include controls for SES, marital history, functional health, and other predictors listed in Appendix Table A1.
Number of network members is treated as the exposure variable.
Note that this model also includes an interaction b/w age and avg. frequency of interaction w/net members.
Number of possible relationships among network members, given network size, is treated as the exposure variable.
Seemingly unrelated estimation test of whether including the life-course factors significantly alters the association b/w age and connectedness.
