Univariate ANOVA

Hello,

I am trying to do a simple Univariate ANOVA, my dependable variable is
continuous and I have three independent variables which are categorical.
My data looks something like this:
0 0 0 0.79
1 0 0 0.97
0 1 0 1.26
1 1 0 1.03
0 0 1 0.12
1 0 1 0.11
0 1 1 0.27
1 1 1 0.31

I keep on getting this result where the F and P values are dots (.) and it
says a. R Squared = 1.000 (Adjusted R Squared = .)

Could anyone please let me know where am I going wrong.

Thanks!
Nsaha

Re: Univariate ANOVA

ARGH! What is your syntax?? If you're using the menus, copy the syntax command from the output and post to the list.

You are posting a question without showing us what you are doing (ie posting your syntax).
Leaving us to throw dice and abuse our imagination.
That is wrong!

I asssume you have many more obserations for each combination of independent variables?

With N=8 and fitting a saturated model (ME, 2 way and the 3 way) you end up with 0 DF Error. That will result in an undefined F since MSE can't be computed.
Review your statistics.
Compare:
UNIANOVA
dv BY a b c
/METHOD = SSTYPE(3)
/INTERCEPT = INCLUDE
/CRITERIA = ALPHA(.05)
/DESIGN = a b c a*b a*c b*c a*b*c .

*VS*:

UNIANOVA
dv BY a b c
/METHOD = SSTYPE(3)
/INTERCEPT = INCLUDE
/CRITERIA = ALPHA(.05)
/DESIGN = a b c a*b a*c b*c .

*VS*.

UNIANOVA
dv BY a b c
/METHOD = SSTYPE(3)
/INTERCEPT = INCLUDE
/CRITERIA = ALPHA(.05)
/DESIGN = a b c .

I suspect that N=8 ergo the undefined F (0 dfe) and R^2=1 even adding 1 more case to the mix would alter this. OTOH: OP needs to hit the books!
