Webb1 feb. 2024 · For example, consider the Cauchy distribution, which is pathological in the sense that both its first and second moments are undefined, i.e. σ 2 ≮ ∞ \sigma^2 \nless \infty σ 2 ≮ ∞. If you take the code in the Appendix and re-run it with np.random.standard_cauchy, you will find that S n S_n S n is not Gaussian distributed. 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).
