Hi,

I am currently studying on Pharmacokinetic Analysis. My teacher gave me a sample Cmax Data for use in studying. I was tasked to compute for the bioequivalence using the protocol in this link:

FDA Draft Guideline

I got the following values for the reference variability and CI.

reference = 0.378573
CI = 34.55646

According to him these are the wrong values. It should have been 0.452 and -0.16794 respectively.

I have tried recomputing it a number of times already. I also used the SAS code as indicated in the guide. Am I missing something? Is there supposed to be some other implied computation that I am not doing? Below is a link to some of the files I have used for computation as well as the sample data he gave.

Thank you very much in advance to anyone who can help me.

Thanks and Regards,
Paolo
