... The marginal distribution p.y/ is an integral. As long as the integral is finite, the particular value of the integral does not provide any additional information about the posterior distribution. Hence, p. jy/ can be written up to an arbitrary constant, presented here in proportional form as: ...

... A very common application of the binomial distribution in statistics is when we are counting the number of times a particular outcome occurs in a random sample from some population, for example, the number of defective CDs in a sample of size 10 from a population of 10,000. In cases like this, the s ...
