Table 5. MAINTENANCE OF FRIENDSHIPS.

Standard logistic regressions for maintenance of friendships between consecutive network observations. Est. means estimated coefficient and SE is estimated standard error..

Wave 1 - Wave 2
	Model 1		Model 2		Model 3
	Est	SE	Est	SE	Est	SE
Intercept	0.40	0.06***	−0.71	0.36	−1.07	0.60
Log-Dist	−0.19	0.04***	−0.17	0.04***	0.10	0.36
Same School			1.14	0.36*	1.50	0.60
School * Log-Dist					−0.28	0.36

Wave 2 - Wave 3
	Model 1		Model 2		Model 3
	Est	SE	Est	SE	Est	SE
Intercept	0.46	0.06***	−0.75	0.33	−0.61	0.49
Log-Dist	−0.05	0.04	−0.03	0.04	−0.15	0.31
Same School			1.24	0.33***	1.10	0.49
School * Log-Dist					0.12	0.31

The stars indicate the level of significance at which the estimated parameter is different from zero:

^*p – val < 0.01

^**p – val < 0.001

^***p – val < 0.0001

Same School is an indicator variable taking the value of 1 if the pair of adolescents attended the same school and 0 otherwise. School * Log-Dist is an interaction between the logarithm of distance and belonging to the same school.
