anova power calculations
...A though it is giving me
a different result though than SAS, 0.8759455 versus 0.680.
So is there a straightforward way to compute the power of an unbalanced
ANOVA? If there isn't, does anyone have any idea what is wrong with my code?
The SAS I am comparing it to is:
Data Dep;
Input cue $ mean uneven_weight;
datalines;
A 17.5 1
B 19 1
C 25 5
D 20.5 1
;
proc glmpower;
class cue;
model mean = cue;
weight uneven_weight;
power
stddev = 9
alpha = 0.05
ntotal= 80
power = .;
run;
Any help would be much appreciated.
