This paper studies in detail simulation methods for simulating tail probability and tail mean of both univariate and bivariate compound variables. We first reviewed some basic variance reduction methods, then we proposed several novel combinations of variance reduction methods specifically for...

Graphitic onion-like carbon (GOC) present multi-shelled concentric polyhedral morphology with the particle size of 2.67 µm to 10.10µm. Used as anode material for lithium-ion batteries (LIBs) and potassium-ion batteries (PIBs), the specific concentric structure can effectively avoid interlayer...

Increasing evidence showed that litter positioning (above- vs. below-ground) would substantially influence decomposition process especially in drylands. However, it is not clear how positioning interacts with litter quality and incubation period controlling a long-term decomposition process. A...

The ambition of this paper is to catch hidden information inside the Securities and Exchange Commission’s (SEC)13F public holding data in order to construct an equity portfolio that maximizes returns. The 13F ling data give us the quarterly stock trading decisions of included funds, but...

Improved kernel-based estimates of integrated squared density derivatives are obtained by reinstating non-stochastic terms that have previously been omitted, and using the bandwidth to (approximately) cancel these positive quantities with the leading smoothing bias terms which are negative. Such...

The sliced mean variance–covariance inverse regression (SMVCIR) algorithm takes grouped multivariate data as input and transforms it to a new coordinate system where the group mean, variance, and covariance differences are more apparent. Other popular algorithms used for performing graphical...
