Properties of Census Dual System Population Size Estimators
Capture-recapture Correlation Bias Erroneous enumeration Kernel smooth- ing Model bias
2016/1/19
We evaluate three population size estimators, including the post-stratification and lo-gistic regression estimators which has been or will be implemented in the US Census dual system surveys. Conditio...
iPosture:The Size of Electronic Consumer Devices Affects Our Behavior
Technology Behavior Health Size Outcome or Result Power and Influence
2015/4/28
We examined whether incidental body posture, prompted by working on electronic devices of different sizes, affects power-related behaviors. Grounded in research showing that adopting expansive body po...
Ground-state properties of small-size nonlinear dynamical lattices
Particles nonlinear lattice discrete nonlinear schrodinger equation nonlinear optical wave condensate
2014/12/25
We investigate the ground state of a system of interacting particles in small nonlinear lattices with M⩾3 sites, using as a prototypical example the discrete nonlinear Schrödinger equation...
Power-law of Aggregate-size Spectra in Natural Systems
aggregate-size fractal dimension river basins networks systems allometry
2013/4/28
Patterns of animate and inanimate systems show remarkable similarities in their aggregation. One similarity is the double-Pareto distribution of the aggregate-size of system components. Different mode...
NetSimile: A Scalable Approach to Size-Independent Network Similarity
NetSimile Scalable Approach Size-Independent Network Similarity
2012/11/23
Given a set of k networks, possibly with different sizes and no overlaps in nodes or edges, how can we quickly assess similarity between them, without solving the node-correspondence problem? Analogou...
On Set Size Distribution Estimation and the Characterization of Large Networks via Sampling
On Set Size Distribution Estimation Characterization large Networks via Sampling
2012/11/22
In this work we study the set size distribution estimation problem, where elements are randomly sampled from a collection of non-overlapping sets and we seek to recover the original set size distribut...
Evolutionary Model of the Growth and Size of Firms
firm size distribution firm growth Gibrat's law product growth size-variance relationship growth rate distribution, Subbotin distribution Laplace distribution Pareto distribution price distribution human activity evolutionary economics product life cycle learning curve market size Hendersons law law of diminishing returns competitive markets
2012/9/18
The key idea of this model is that firms are the result of an evolutionary process. Based on demand and supply considerations the evolutionary model presented here derives explic...
Dependence of lead time on batch size studied by a system dynamics model
batch processing inventory management modelling bullwhip effect
2011/10/29
Most planning models treat lead time as a constant independent of workload, but the resulting order rate implies capacity utilisation that, in turn, affects the lead time. An important factor that det...
Efficient adaptive designs with mid-course sample size adjustment in clinical trials
adaptive design conditional power futility Kullback-Leibler information sample size re-estimation
2011/6/17
Adaptive designs have been proposed for clinical trials in which the nuisance parameters
or alternative of interest are unknown or likely to be misspecified before the trial. Whereas most
previous w...
The System Size Distribution for M/G/1 Queueing System under N-Policy with Startup/Closedown
Queue-Length N-Policy Stochastic Decomposition Recursion Expression Leibniz Formula
2013/2/23
This paper develops a new method for calculating the system size distribution on two different M/G/1 queueing system under N-policy with general startup/closedown. Firstly, the stochastic decompositio...
Trade intensity, country size and corruption
corruption governance openness trade population
2010/11/5
Several authors claim to provide evidence that governmental corruption is less severe in countries where trade intensity is higher or populations are smaller. We argue that theory is highly ambiguous ...
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...
Analysis of dependence among size, rate and duration in internet flows
Correlation analysis extremal dependence analysis
2010/10/19
In this paper we examine rigorously the evidence for dependence among data size, transfer rate and duration in Internet flows. We emphasize two statistical approaches for studying dependence, includi...
Robust Independent Component Analysis by Iterative Maximization of the Kurtosis Contrast with Algebraic Optimal Step Size
Atrial fibrillation (AF) blind source separation (BSS) independent component analysis (ICA) iterative optimization kurtosis
2010/3/10
Independent component analysis (ICA) aims at decomposing an observed random vector into
statistically independent variables. Deflation-based implementations, such as the popular one-unit FastICA algo...
Size-biased branching population measures and the multi-type x\logx condition
general branching process immigration size-biased measure xlogx condition
2010/3/9
We investigate the x log x condition for a general (Crump–Mode–Jagers) multi-type branching
process with a general type space by constructing a size-biased population measure that relates
to the ord...
