Posterior probabilityis theconditional probabilityan event will happen after all evidence or background information has been taken into account. To put that another way: if we know the conditional and unconditional probabilities of one event in advance, we can calculate the conditional probabilities for...
The centerpiece was a number, now called the Bayes factor, which is the posterior odds of the null hypothesis when the prior probability on the null is one-half. Although there has been much discussion of Bayesian hypothesis testing ... RE Kass,AE Raftery - 《Journal of the American Statist...
Alpha is the probability of saying on the outcome of a test there is an effect for the manipulation, while on population level there actually is none. 1-alpha is the chance to accept the null hypothesis when it is true –a correct decision-. This is called reliability. A type 2 error,...
are collected continuously over time, the experiment can be analysed after each mini experiment, incorporating prior data and thereby accumulating information step by step. Importantly, however, to avoid introducing any experimenter bias through this stepwise knowledge gain, interim analyses should ideally ...
Find the posterior distribution of θ if we assume the un-informative prior h(θ) = 1. Find the Bayes estimate for θ under the square loss function. How to calculate dependent probability? Find the variance of the following probability distribution: Find the variance of the ...
You can calculate empirical probability by creating a ratio between the number of ways an event happened to the number of opportunities for it to have happened. In other words, 75 heads out of 100 coin tosses come to 75/100= 3/4. Or P(A)-n(a)/n where n(A) is the number of tim...

Banks often calculate an EAD value for each loan and then use these figures to determine their overall default risk. Special Considerations The Probability of Default and Loss Given Default PD analysis is a method used by larger institutions to calculate their expected loss. A PD is assigned to...
Having enough people respond to your survey is essential. Here’s the need-to-know on response rates and how to boost them.
probability distributions. One approach is to calculate a distance measure between the two distributions. This can be challenging as it can be difficult to interpret the measure. Instead, it is more common to calculate a divergence between two probability distributions. A divergence is like a ...
