Variate-x 2023年03月12日 感觉想通了一些事,可以很轻松的继续生活了 “忽有说话的欲望,环顾四周,却无一人” 没人能听我这些矫情的感言, 那就悄咪咪的在这里说给自己听吧 孤独是人类进步必须认清的本质, 这也将会成为我人生的旋律, 我会尽全力接受她,并享受她 希望在这和过程中,我能发现并赋予自己价值 认...
View Solution Let sigma be the standard deviation of n observations. Each of the n observation is multiplied by a constant c. Then the standard deviation of the resulting numbers is View Solution The standard deviation of variatexiis σ. Then standard deviation of the variateaxi+bcwherea,b,ca...

In this paper, we determine the symmetrised density of doubly noncentral singular matrix variate beta type I and II distributions under different definitions. As particular cases we obtain the noncentral singular matrix variate beta type I and II distributions and the cor...
Therefore, this study aims to develop a flexible four-variate joint distribution function of the regional stochastic nature of drought. Using run theory, drought duration, severity, peak, and inter-arrival time were abstracted from the Standardized Precipitation Evapotranspiration Index (SPEI) aggregated...
The analogous matrix variate distributions and their characteristic functions are derived in the sequel and are dual to each other in the sense of a simple Duality Theorem. This theorem can thus be used to yield the derivation of the characteristic function of the t-distribution and is the ...

Matrix variate distributions Random matrices appear in the theory and in applications of multivariate analysis. A common-occurring example is the p脳n "sample observation matrix", in which each of its n columns is an independent sample from a given p-variate distrib......
A poisson variate x is such that P(x=2)=9P(x=4)+90.P(x=6) then mean and standard deviation are
