## Ratio calculation of fully replicate study [RSABE / ABEL]

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.

$$x/y=\exp (\log_{e}x-\log_{e}y)\;\left\{x,y \in \mathbb{R}^{+} \right\}\; {\color{red}{\neq}}\log_{e}x/\log_{e}y$$
