Webb8. Cauchy distribution. A Cauchy random variable takes a value in (−∞,∞) with the fol-lowing symmetric and bell-shaped density function. f(x) = 1 π[1+(x−µ)2]. The expectation of Bernoulli random variable implies that since an indicator function of a random variable is a Bernoulli random variable, its expectation equals the probability ... WebbThe main goal of this paper is to study the spectral properties of a large random matrix with i.i.d. Cauchy entries. In other words we consider a rectangular m×n matrix A = (aij), 1 ≤ i ≤ m, 1 ≤ j ≤ n, where {aij} are independent identically distributed Cauchy random variables with the probability density f(x) = 1 π(1+x2).
