Bayesian Statistics Question

Question

Suppose that you are about to analyze new data from an experiment, with particular interest in estimating a parameter β that varies by group. Published data suggests that β has a mean of about 1.2 and a standard deviation of about 0.8. The observed values corresponding to β in your data have a mean of about 1.0 and a standard deviation of about 0.9. If you use a prior of a normal distribution with a mean of 1.0 and a standard deviation of 0.9, then you are using a method known as___________________

Answer 1

Note that the paremeters of the prior come, not form historical data, but from the sample. This is known as empiricl Bayes.
