In order to find the proper number of lags for the VAR (and also to the BVAR), a Log likelihood ratio – test (LR-test) is done with results from Schwarz and Akaike criteria and it suggests just one lag, as seen in the Table 7 below. Table 7. Likelihood Ratio (BR) No Lags H0...
quantization scheme for log-likelihood ratios which optimizes the trade-off between rate and accuracy in the sense of rate distortion theory: as distortion measure we use mutual information to determine quantization and decision levels maximizing mutual information for a given rate over a Gaussian ...
Summary: We derive a log-likelihood function-based classification algorithm for classifying quadrature amplitude modulation (QAM) signals buried in additive white Gaussian noise. We derive the amplitude density functions of received QAM signals first, then develop the required statistics for signal classifi...

aIt is worth noting that, in the case of a Log-Normal distribution, a multivariate Gaussian Copula allows to obtain simulated damage values, which correspond to the values obtainable by randomly drawing from a multivariate Log-Normal distribution. 它值得注意到,在记录正常的发行情况下,一个多维分布的...

The covariance matrix of the Gaussian distribution is \sigma ^{2}_{1} \Sigma _{1}. Diagonal elements of Σ1 are 1 and off diagonal elements are ρ1. Heterogeneous markers are similar to global markers in class 0 but comprise c subclasses in class 1, where in each subclass certain ...
