Dear all, I want to know why we take median of Tmax instead of mean in PK analysis. please give the guidance about it. Thanks in advance, Priyanka Bhavsar -- Edit: Category changed. [Helmut] |

Dear Priyanka! ❝ I want to know why we take median of Tmax … Tmax is strongly dependent on the chosen sampling scheme. The sampling distribution of Tmax will always be a discrete one (see here). ❝ … instead of mean in PK analysis. The (arithmetic) mean is the best unbiased estimator of the location of the normal distribution – but it can be substantially sub-optimal for distributions close to the normal and will be inferior for all discrete distributions. — Dif-tor heh smusma 🖖🏼 Довге життя Україна! ![[image]](https://static.bebac.at/pics/Blue_and_yellow_ribbon_UA.png) Helmut Schütz ![[image]](https://static.bebac.at/img/CC by.png) The quality of responses received is directly proportional to the quality of the question asked. 🚮 Science Quotes |
