Uncorrelated components are obtained from the original drilling process signals using the principle component analysis; then, the distribution of components is estimated using the MGGD; afterwards, the KLD is c
3.2 The multivariate Gaussian (normal distribution) Murphy calls it MVN. 3.2.1 Definition N(y∣μ,Σ)≜1(2π)D/2|Σ|1/2exp[−12(y−μ)⊤Σ−1(y−μ)]\mathcal{N}(\boldsymbol{y} \mid \boldsymbol{\mu}, \boldsymbol{\Sigma}) \triangleq \frac{1}{(2 \pi)^{D / 2...
3.1a. The Multivariate Gaussian Density in the Complex Domain Consider the complex scalar random variables. Letwherexj1,xj2are real and. LetE[xj1] = μj1,E[xj2] = μj2and. Let the variances be as follows:. For a complex variable, the variance is defined as follows:...

In the next section, we specify a distribution for the factor-based Sato subordinated Brownian motion. 6.2 Normal inverse Gaussian case We specify the factor-based Sato subordinator to have the same unit time distribution of the factor-based \rho \alpha -NIG in Luciano and Semeraro [21]. Let...

(Mutschler, 2018) provides analytical expressions for higher order cumulants for non-Gaussian or nonlinear (pruned) solutions to DSGE models to provide means to gain more information for calibration and estimation. In this paper we derive a general formula for the fourth-order cumulants of the ...

The most common and convenient assumption is the Gaussian distribution. For a Gaussian vector, the assumption of independent coordinates is equivalent to the assumption of uncorrelated coordinates. Such an equivalence is no longer true when considering a multivariate Student distribution. We thus consider...
The formula for the confidence region on θ is (8){θ∈Θ:(θ−θˆ)TX[XT∑−1X]−1XT(θ−θˆ)≤Fp+1,n−p−1,α}, where Fp + 1, n − p − 1, α is the (1 − α)-percentile point obtained from an F-distribution with p + 1 and n − p − 1...
