Mixed-effect models predicting net transfers (calories per day) from older nuclear family i to younger nuclear family j, as a function of familial net need for each relationship category. Model 1 reports the mean net transfer within each relationship type. Models 2 and 3 report the standardized regression coefficient β for the relationship between net need and net transfers for donors and receivers within each relationship category. p-values indicate whether the mean or standardized regression coefficient β deviates significantly from the null expectation of zero.
