Dear Munjal,
You should use the pwr package with the following code :library(pwr)
# lower
pwr.2p.test(h =ES.h(0.3, 0.2), n = 500, sig.level = 0.05, power = NULL,
alternative = c("two.sided"))#upperpwr.2p.test(h =ES.h(0.3, 0.4), n = 500,
sig.level = 0.05, power = NULL, alternative = c("two.sided"))
Maybe you could use G*power :Lower case 1-beta = 0.9557076Upper one 1-beta=
0.9134817
Hope this help,
Adrien Bonache.

Objet : [R] Power Calculation: Binomial Proportions (2 sided exact test for
equivalence)
Dear R-Sig-teaching users,
I am an intermediate level R user.
I am performing the power calculations for the Binomial proportions (2
sided).
I want to find the Power using the Exact test for the Equivalence of
Binomial proportions.
I do have the SAS code which is generating the Power for me but i am unable
to find the Similar code in R.
I need help for finding the similar computation in R.
My SAS code.
proc power;
onesamplefreq test = equiv_exact
alpha = 0.05
proportion = 0.30
lower = 0.2
upper = 0.4
ntotal = 500
power = .;
run;
Can somebody helkp me by providing the R code for the similar calculation ?
Thank you.
MJ
