WebThe function $\exp\Big(-\frac{(x-\mu)^2}{2\sigma^2}\Big)$ is (a scaled version of) the density function of the normal distribution. ... Therefore normal distributions are everywhere in statistics. In bayesian statistics, many posterior distributions of parameters are approximately normal, or can be assumed to be. Share. Cite. Improve this answer. WebTheorem: Let X X be a random variable following an exponential distribution: X ∼Exp(λ). (1) (1) X ∼ E x p ( λ). Then, the mean or expected value of X X is E(X) = 1 λ. (2) (2) E ( X) = 1 λ. Proof: The expected value is the probability-weighted average over all possible values: E(X) = ∫X x⋅f X(x)dx. (3) (3) E ( X) = ∫ X x ⋅ f X ( x) d x.

For example, suppose we roll a dice one time. If we let x denote the number that the dice lands on, then the probability that the x is equal to different values can be described as follows: P (X=1): 1/6. P (X=2 ...
