Hi Mithu,
» […] how to calculate ratio of fully replicate study in excel?
» I have prepared one excel sheet in which i have put formula to calculate Partial AUC and AUC0-t.
» I am getting correct PK for CMax & AUC's in line with SAS out put but when i am calculating Ratio, it is not matching with SAS out put.
Without knowing your SAS code it would be reading tea leaves. Why on earth do you want to use Excel?
» Process followed to calculate ratio in excel is as follows:
» 1. from two T and two R taking average and then taking ratio of T /R.
» 2. Other case, i had also converted average of both T & R in LN and then taken ratio of LN T & LN R.
$$x/y=\exp (\log_{e}x-\log_{e}y)\;\left\{x,y \in \mathbb{R}^{+} \right\}\; {\color{red}{\neq}}\log_{e}x/\log_{e}y$$
