Figure 1: Solld red curve is a Cauchy density function with z10 andT The dashed
curve is a Gaussan with the same peak as the Gaussian (1/m) with mean-10 and variance
-/2. The Cauchy has heavier tails.
The Cauchy distribution is an interesting example of a
distribution for which both the mean and the variance are
undefined. Which statement best describes what it means
for the mean of a probability density function to be
undefined?
Select one:
O A. The gradient of the pdf at the location parameter x0 is
undefined
O B. The mean of the distribution is infinite
O C. The integral f x* f(x) dx from - infinity to infinity where f(x) is
a Cauchy distribution diverges
O D. The area under the probability density function is undefined
O E. The integral f f(x) dx - infinity to infinity where f(x) is a
Cauchy distribution diverges
