Hi.. I am a student and so, if my question sounds no-technical or stupid, kindly understand... 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. |

Dear Snigdhasantra! ❝ 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:
