Degrees of freedom summary

CFA Level II
#1

Can someone verify the degrees of freedom when looking up critical values for all the tests?

n = observations k = slopes

T-test

df = n - (k+1) [note: is 1 due to the intercept?]

F-test

numerator df = k denominator df = n - (k+1) [note: is 1 due to the intercept?]

Chi squared (heteroskedasticity)

df = k

Durbin-Watson (serial correlation)

k is number of slopes? n is observations?

I’m not missing anything else, am I?

#2

Nope, you’re absolutely correct and Yes, 1 is always for intercept.

Thanks for the summary
