Country: WebbWith small sample size the posterior distribution, and thus also the credible intervals, are almost fully determined by the prior; only with the higher sample sizes the data starts to override the effect of the prior distribution on the posterior. Of course the credible intervals do not have to always be 95% credible intervals.
