How to Deal with the Curse of Dimensionality of Likelihood Ratios in Monte Carlo Simulation
Cross-entropy Rare-event probability estimation Screening Simulation
2015/7/6
In this work we show how to resolve, at least partially, the curse of dimensionality of likelihood ratios (LRs) while using importance sampling (IS) to estimate the performance of high-dimensional Mon...
EigenPrism:Inference for High-Dimensional Signal-to-Noise Ratios
EigenPrism High-Dimensional Signal Noise Ratios
2015/6/17
Consider the following three important problems in statistical inference, namely, constructing confidence intervals for (1) the error of a high-dimensional (p > n) regression estimator, (2) the linear...
A note on monitoring ratios of Weibull percentiles
Bayesian Estimators Statistical Process Control Weibull Distrib ution
2013/6/14
This note introduces a new Bayesian control chart to compare two processes by monitoring the ratio of their percentiles under Weibull assumption. Both in-control and out-of-control parameters are supp...
Estimating the scaling function of multifractal measures and multifractal random walks using ratios
namely mutiplicative cascades structure function
2011/3/24
In this paper we prove central limit theorems for bias reduced estimators of the structure function of several multifractal processes, namely mutiplicative cascades, multifractal random measures, mult...
On the Regular Variation of Ratios of Jointly Frechet Random Variables
Regular variation multivariate Frechet distribution spectral
2011/3/18
We provide a necessary and sufficient condition for the ratio of two jointly alpha-Frechet random variables to be regularly varying. This condition is based on the spectral representation of the joint...
A BEHAVIORAL COMPARISON OF FINANCIAL RATIOS FOR DIFFERENT SIZE PRIVATELY-HELD RETAIL AND SERVICE BUSINESSES

2009/11/30
An analysis was conducted to evaluate the cross-sectional variations of financial
ratios among different size private companies. The study examines four ratio
categories for the retail and servic...

Muliere and Scarsini’s bivariate Pareto distribution：sums，products，and ratios
incomplete beta function Gauss hypergeometric function Muliere and Scarsini’s bivariate Pareto distribution products of random variables ratios of random variables sums of random variables
2009/2/23
We derive the exact distributions of R = X + Y, P = X Y and W = X/(X + Y) and the corresponding
moment properties when X and Y follow Muliere and Scarsini’s bivariate Pareto distribution. The express...
Working Late: Do Workplace Sex Ratios Affect Partnership Formation and Dissolution?
Working Late Workplace Sex Ratios Partnership Formation
2016/3/7
In this paper, I analyze the association between workplace sex ratios and partnership formation and dissolution. I find that the risk of dissolution increases with the fraction of coworkers of the opp...
Is the Marginal Child More Likely to be Murdered?: An Examination of State Abortion Ratios and Infant Homicide
Marginal Child More Likely Murdered Examination State Abortion Ratios Infant Homicide
2016/3/7
We examine whether abortion removes from the population those infants most at risk of homicide. As part of our identification strategy, we find that abortion reduces the number of unwanted births, est...
