Using the Continuous Spectrum to “Feel” Integrability: the Effect of Boundary Conditions
Test model integrability partial differential differential difference equations of continuous spectrum
2014/12/29
The scope of this work is to propose a method for testing the integrability of a model partial differential (PDE) and/or differential difference equation (DDE). For monoparametric families of PDE/DDE’...
Estimating treatment effect heterogeneity in randomized program evaluation
Causal inference individualized treatment rules LASSO moderation variable selection
2013/6/14
When evaluating the efficacy of social programs and medical treatments using randomized experiments, the estimated overall average causal effect alone is often of limited value and the researchers mus...
Smoothing effect of Compound Poisson approximation to distribution of weighted sums
characteristic function concentration function compound Poisson distribution Kolmogorov norm weighted random variables.
2013/4/27
The accuracy of compound Poisson approximation to the sum $S=w_1S_1+w_2S_2+...+w_NS_N$ is estimated.
Here $S_i$ are sums of independent or weakly dependent random variables, and $w_i$ denote weights...
Nonparametric testing for no-effect with functional responses and functional covariates
functional data regression nearest neighbors smoothing nonparametric testing
2012/11/22
This paper studies the problem of nonparametric testing for the no-effect of a random functional covariate on a functional response. That means testing whether the conditional expectation of the respo...
A Poisson Mixed Model with Nonnormal Random Effect Distribution
Count data Generalized log-gamma distribution Multivariate negative binomial distribution Overdispersion Random-effect models
2011/6/17
We propose in this paper a random intercept Poisson model in which the random effect distribution
is assumed to follow a generalized log-gamma (GLG) distribution. We derive the first two moments
for...
Linearization effect in multifractal analysis: Insights from Random Energy Model analysis
Statistical Mechanics (cond-mat.stat-mech) Probability (math.PR) Statistics Theory (math.ST)
2010/12/17
The analysis of the linearization effect in multifractal analysis, and hence of the estimation of moments for multifractal processes, is revisited borrowing concepts from the statistical physics of di...
Effect of Wind Intermittency on the Electric Grid：Mitigating the Risk of Energy Deficits
California renewable energy risk analysis systems engineering wind power generation
2010/3/10
Successful implementation of California’s
Renewable Portfolio Standard (RPS) mandating 33 percent
renewable energy generation by 2020 requires inclusion of a
robust strategy to mitigate increased r...
Long Strange Segments,Ruin Probabilities and the Effect of Memory on Moving Average Processes
Long Strange Segments Ruin Probabilities Effect Memory Moving Average Processes
2010/3/11
We obtain the rate of growth of long strange segments and the
rate of decay of infinite horizon ruin probabilities for a class of infinite moving
average processes with exponentially light tails. Th...
Relative Age Effect in Elite Sports:Methodological Bias or Real Discrimination?
Relative Age Effect Soccer Discrimination Bias
2010/3/9
Sport sciences researchers talk about a relative age effect when they observe a biased
distribution of elite athletes’ birthdates, with an over-representation of those born at the
beginning of the c...
Does the effect of micronutrient supplementation on neonatal survival vary with respect to the percentiles of the birth weight distribution?
percentiles counterfactual Bayesian computation
2009/9/22
The methods in this paper are motivated by a double-blind randomized
community trial in rural Nepal (Christian et al 2003a,b). The investigators imple-
mented an intervention program to evaluate ben...
On the Effect of Random Alternating Perturbations on Hazard Rates
Hazard rates telegraph process dichotomous noise estimatedhazard rates confidence bands
2010/4/26
We consider a model for systems perturbed by dichotomous noise, in which the
hazard rate function of a random lifetime is subject to additive time-alternating perturbations
described by the telegrap...
Orthogonal main effect plans on blocks of small size
main effect plans partial orthogonality
2010/4/26
In this paper we define the concept of orthogonality between two factors
”through another factor”. Exploiting this property we have been able to obtain
orthogonal main effect plans (OMEP) on non-ort...
