... can see that the posterior distribution is a gamma distribution with shape parameter i xi + α and rate parameter n + ν! In the Bayesian paradigm, all information about Λ is contained in the posterior. We can estimate the parameter e.g. by the mean or mode (posterior mean and posterior mode, respecti ...

(a) 50 50 50 50 50 (b) 10 20 50 80 90 (2) The distributions are obviously very different. (a) Measures of dispersion or ...

Some Basic Statistics for Non-Statisticians
... Suppose we take a sample of our Subjects and measure their Blood Alcohol levels. We could calculate the mean of these values. If we take another sample of these subjects we will also get a mean but it is likely that the mean will not be the same. Depending on the variation in data you will get a num ...
