Consider the Cauchy family defined in Section 3.3. This family can be extended to a location-scale family
Question:
The mean and variance do not exist for the Cauchy distribution. So the parameters μ and Ï2 are not the mean and variance. But they do have important meaning. Show that if X is a random variable with a Cauchy distribution with parameters μ and Ï, then:
(a) μ is the median of the distribution of X, that is, P(X > p) = P(X (b) μ + Ï and μ - Ï are the quartiles of the distribution of X, that is, P(X > μ + Ï) = P(X
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
