WebSuppose I have only two data describing a normal distribution: the mean $\mu$ and variance $\sigma^2$. I want to use a computer to randomly sample from this distribution such that I respect these two statistics. It's pretty obvious that I can handle the mean by simply normalizing around 0: just add $\mu$ to each sample before outputting the sample. Web1 de dic. de 2024 · Since the parallel sampling framework produces a full Bayesian or bootstrap distribution of model-averaged predictions, there is no need to rely on approximation methods. For example, Bornkamp [ 3 ] calculated confidence intervals for BIC-based model averaging using a normal approximation, which implies symmetric …
