Calculate the Fisher information in a sample of size n. Techniques for estimating sample size and performing power analysis depend mainly on the design of the study and the main measure of the study. The tables are based on exact power calculations for Fishers Exact Test.
1 N 3 displaystyle 1 over sqrt N-3 where N is the sample size and ρ is the true correlation coefficient.
The second method is to use the formula for the sample size for the mean. A collection of sample size tables are presented for designing comparative trials when the event rates p 1 and p 2 are low. Calculate the Fisher information in a sample of size n. The second method is to use the formula for the sample size for the mean.
