Dear all
I am very beginner user of R I want to calculate the power of t-test using power.t.test function. It is stated in the manual that the argument (n) is the number of observations per group. Infact I have a differens number of observations in each group(ie n1<>n2) and another thing is SD the pooled standard deviation of the observations in the two data sets under investigation.
Hope find an answer soon
