Non-parametric tests [Power / Sample Size]
Dear Snigdhasantra!
In the context of bioequivalence, which kind of PK metric are you testing?
The Z test is parametric (based on the normal distribution).
For sample size estimation of nonparametric tests you have two options:

❝ I would like to know if we can calculate sample size in case of a study in which only non-parametric tests (chi square test and Z test) will be applied.
In the context of bioequivalence, which kind of PK metric are you testing?
The Z test is parametric (based on the normal distribution).
For sample size estimation of nonparametric tests you have two options:
- applying asymptotic normal approximations, or
- bootstrapping.

The quality of responses received is directly proportional to the quality of the question asked. 🚮
