Dear colleagues, is there a "convention" for power assumptions in a BE study sample size calculation. I realize this will depend on "risk tolerance" but what do YOU use, e.g., 80%, 90% etc. Regards — Biostatistically Challenged CEO |

Hi Sereng, 80%-90% is what I usually go for. I most often prefer 90% but the guy in the penguin costume prefers 80% and he seems to decide everything. — Pass or fail! ElMaestro |

HI ElMaestro, many thanks for the response. However, I missed the joke about "the guy in the penguin costume". I should have listed to my parents when the implored me to get a good liberal arts education! — Biostatistically Challenged CEO |

Hi Sereng, ❝ I missed the joke about "the guy in the penguin costume". For many years we have a running gag in the forum calling the boss* ‘the guy in the Armani suit’ (© ElMaestro, introduced there). ‘The guy in the penguin costume’ is a new variant.
