Webτ ∼ Gamma(2,1), and µ and τ are independent (that is, the prior density for (µ,τ) is the product of the individual densities). Let us find the full conditional distributions for µ and τ. First, a bit of preliminary setup: The likelihood function is the joint density of the data (given the parameters), viewed as a function of the ... Web14.6 - Uniform Distributions. Uniform Distribution. A continuous random variable X has a uniform distribution, denoted U ( a, b), if its probability density function is: f ( x) = 1 b − a. for two constants a and b, such that a < x < b. A graph of the p.d.f. looks like this: f (x) 1 b-a X a b. Note that the length of the base of the rectangle ... WebThe gamma distribution can be parameterized in terms of a shape parameter α = k and an inverse scale parameter β = 1/ θ, called a rate parameter.
