Dear Statalisters,
Please forgive me if you find this request silly (or basic), but I have
been having some nightmares to figure out how to use ex post "fpower" for
anova.
I have read about the power analysis (e.g. papers, and on
www.ats.ucla.edu), but it looks like I can't do the test because I don't
seem to know how to calculate delta and/or means for my groups. Hence
would really appreciate some help from you.
My anova results are:
.anova nm year
Number of obs = 95 R-squared =
0.0497
Root MSE = .487822 Adj R-squared
= -0.0387
Source | Partial SS df MS F Prob

year | 1.07136314 8 .133920392 0.56

Total | 21.5368421 94 .229115342
where: nm = 2 groups
year = 8 groups
Many thanks in advance,
Aggie
