In general, the PDF of multivariate Gaussian distribution (a.k.a. multivariate normal distribution, MVN) is as below: 1(√2π)ddet(Σ)1/2exp{12(x−μ)TΣ−1(x−μ)}1(2π)ddet(Σ)1/2exp{12(x−μ)TΣ−1(x−μ)} ...

Is there a general formula that can describe the result in the following form? ϕn(x)⋆ϕm(x)=A(n,m,a)ϕn+m(x)ϕn(x)⋆ϕm(x)=A(n,m,a)ϕn+m(x) AA is constant w.r.t xx. AA is function of nn, mm and aa. normal-distribution convolution hermite-polynomials...
The idea is to bring to the infinity, switching from a discrete to a continuous distribution. In order to do that, we first need to expand the binomial coefficient using its factorial form: then, factorial terms should be approximated using the Stirling’s formula: The rest of the derivation...
首先说Gaussian, 说到Gaussian (高斯)这个相必应该是大家耳熟能详的吧,除了那个1+2+...50的故事,还有高斯分布(Gaussian distribution)应该是不会不知道的吧。哦,对了,更多的情况下大家叫正态分布(Normal distribution ). 再说Process,这个词语在数学上多指随机过程(Stochastic process ).简单来讲,随机过程么,就一...

具体来说呢我们在categorical parameter上加上uniform的prior,然后在Gaussian的mean parameter加一个\mathcal{N}(0, +\infty)的prior,然后解出Gibbs sampling的update formula。下面我们稍稍的abuse一下notation,让\mathcal{N}即代表一个distribution,又代表他的pdf。
Secondly, considering normal-gamma priors on the unknown parameters, the computational formula of . 首先,根据Bayes统计推断的基本原理,建立了判断粗差的Bayes方法——后验概率法,然后针对测量平差实际,考虑未知参数的正态-Gamma先验信息,分别给出了非等权独立观测条件下基于均值漂移模型和方差膨胀模型的后验概率...
In statistics, the Gaussian, or normal, distribution is used to characterize complex systems with many factors. As described in Stephen Stigler’s The History of Statistics, Abraham De Moivre invented the distribution that bears Karl Fredrick Gauss’s n
