Dear S'ers,

summary.glm() produces as part of the output a table looking like this:

Value Std. Error t value
(Intercept) -5.6830031 1.01362711 -5.6066014
p1 -0.9077401 0.24053241 -3.7738785
yr 0.1698384 0.08428661 2.0150110
vacc 0.8427123 1.03061219 0.8176813

1. What are the corresponding df for the t value ?
2. Could you please indicate me references about that ?

(I am using S-Plus 4.5 / Win 95).

Thanks in advance and best regards,

Renaud
