Bayesian 2

Question 1

Sequential analysis

Answer 1

you can keep looking at the data because of the updating factor. In normal hypothesis testing this increases you’re type I error. With Bayesian you can look at a plot of how BF evolves as we accumulate knowledge.

Question 2

Uniform prior distributions

Answer 2

Uninformative prior, one line.

Question 3

Domain

Answer 3

Prior distribution is on the same domain as the parameter of interest. For a proportion it’s between 0 and 1. Correlation between -1 and 1 and means till infinity.

Question 4

Stretched Beta Distribution

Answer 4

Data had been stretched on the same domain as the parameter.

Question 5

Truncated stretched beta distribution

Answer 5

one sided hypothesis stretched distribution

Question 6

Delta (Cohen’s d)

Answer 6

Differences between groups; a standardized difference between groups. Goes 0 to 2. Used with a T-test.
