Hi again,
In fact the pwr package do not provide exact test power. So you should
definitely use g*power.
Sincerely,
Adrien.

Maybe you could use G*power :Lower case 1-beta = 0.9557076Upper one 1-beta=
0.9134817
Hope this help,

Thanks for your response, Marc. HG and LG are high-grade/low-grade tumors.
The data has not been collected yet, but will be soon. It's all archived
data that will be pulled from computer records. The IRB wants some mention
of power or sample size, but doing it for this scenario has been a bit o

I am trying to do a power calculation for a survival analysis using a

- I have 2 groups, namely HG and LG

See pwr.t2n.test() in the pwr package.

Hello,
Is there any R function which does power calculation for unbalanced groups (n1
neq n2)? Since power.t.test has n
Number of observations (per group).
Many thanks,

Mind a book reference instead of a software reference?
Look for Bausell and Li's "Power Analysis for Experimental Research"
-- cookbook style power calculations, but has explicit RM ANOVA.

Is there a way to calculate power for repeated
measures ANOVA (2 groups x 7 observations)? I have
searched all over, but all I can find is
power.anova.test, but that would not give accurate
results, right?
Thanks,
Matt Bridgman
