4 февр. 2012 г. · Let the "relative median" be nEα divided by (2/π)nlog(n). Here is a plot of such relative medians as observed in 5,000 simulations of samples up ...

12 янв. 2016 г. · That said, Sn/n does not converge in any sense (almost sure, in probability, in distribution) where Sn is the sum of n i.i.d. Cauchy variables.

3 окт. 2016 г. · The sample means will be themselves Cauchy distributed. In other words, the Cauchy distribution is a stable distribution.

10 сент. 2012 г. · That is, the sum of n independent Cauchy distributions is a Cauchy distribution scaled by a factor of n. If the Cauchy distribution had a ...

20 мая 2023 г. · If X1,…,Xn are i.i.d. standard Cauchy distribution C(0,1), then since Cauchy distribution is closed under independent summation (see the second ...

14 июл. 2023 г. · Suppose Xi are Cauchy(0, γ) IID RV's and let Sn=X1+⋯+Xn be their sum. Does an expression exist for the CDF of the running maximum up to an ...

8 апр. 2021 г. · First you prove that the mean of n iid Cauchy observations, have the same Cauchy distribution. That might be surprising, but the proof is already on site.

28 нояб. 2019 г. · The ratio of two independent zero-mean equal-variance normal random variables is indeed a standard Cauchy random variable.

19 мая 2022 г. · The sum of two independent Student t variables has a Student t distribution (up to scale) only when both variables have one degree of freedom.
