¹Moran’s I adjusted for bias dependent on network sample size, −1 / (N – 1).

²Waves 3–7

b Net Std Dev = unstandardized regression coefficient for the network specific standard deviation of the attribute

b log_n = unstandardized regression coefficient natural log of the number of students in this school grade cohort

b log_n² = unstandardized regression coefficient square of the log_n, after subtracting mean log_n

Standard errors in parentheses.

Wald χ² = Joint significance test for the overall relationship of network size to similarity between friends.
