The shaping and functional consequences of the dosage effect landscape in multiple myeloma
shaping functional consequences dosage effect landscape multiple myeloma
2016/1/25
In this paper we study the conditional limit theorems for critical continuous-state branching processes with branching mechanism ψ(λ) = λ 1+α L(1/λ)where α ∈ [0,1] and L is slowly varying at ∞. We pro...
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...
Behavior patterns of online users and the effect on information filtering
bipartite networks reshuffling process information filtering
2011/7/19
Understanding the structure and evolution of web-based user-object bipartite networks is an important task since they play a fundamental role in online information filtering. In this paper, we focus o...
Distribution fitting 13. Analysis of independent, multiplicative effect of factors. Application to effect of essential oils extracts from plant species on bacterial species. Application to factors of antibacterial activity of plant species
factor analysis Negative Binomial distribution Poisson distribution
2011/7/5
A factor effect study was conducted on a set of observations at the contingency of a series of plant species and bacteria species regarding the antibacterial activity of essential oil extracts.
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...
An empirical Bayes mixture method for effect size and false discovery rate estimation
Empirical Bayes false discovery rate effect size estimation
2010/10/19
Many statistical problems involve data from thousands of parallel cases. Each case has some associated effect size, and most cases will have no effect. It is often important to estimate the effect siz...

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...
