Properties of neutrality tests based on allele frequency spectrum
Coalescent theory Site frequency spectrum Population genetics Statistical power Summary statistics
2010/11/9
One of the main necessities for population geneticists is the availability of statistical tools that enable to accept or reject the neutral Wright-Fisher model with high power.
A Bregman Extension of quasi-Newton updates II: Convergence and Robustness Properties
A Bregman Extension quasi-Newton updates II Convergence Robustness Properties
2010/10/19
We propose an extension of quasi-Newton methods, and investigate the convergence and the robustness properties of the proposed update formulae for the approximate Hessian matrix. Fletcher has studied ...
Exact properties of Efron's biased coin randomization procedure
Accidental bias exact distribution theory randomization test
2010/10/14
Efron [Biometrika 58 (1971) 403--417] developed a restricted randomization procedure to promote balance between two treatment groups in a sequential clinical trial. He called this the biased coin des...
Thermodynamic properties of finite binary strings
Thermodynamic properties finite binary strings
2010/3/9
Thermodynamic properties such as temperature, pressure, and internal
energy have been defined for finite binary strings from equilibrium distribution
of a chosen computable measure. It is demonstrat...
Optimal properties of centroid-based classifiers for very high-dimensional data
Centroid method classification discrimination distance-basedclassifiers high-dimensional data location differences minimax performance
2010/3/11
We show that scale-adjusted versions of the centroid-based classi-
fier enjoys optimal properties when used to discriminate between two
very high-dimensional populations where the principal differen...
Minimax properties of beta kernel density estimators
Beta Kernel Density Minimax estimation
2010/3/9
In this paper, we are interested in the study of beta kernel estimators from
an asymptotic minimax point of view. It is well known that beta kernel estimators
are—on the contrary of classical kernel...
Asymptotic efficiency and finite-sample properties of the generalized profiling estimation of parameters in ordinary differential equations
Ordinary differential equations parameters estimation profiling procedure consistency asymptotic normality
2010/3/18
Ordinary differential equations (ODEs) are commonly used to
model dynamic behavior of a system. Because many parameters are
unknown and have to be estimated from the observed data, there
is growing...

Characterisations of the geometric distribution using distributional properties of the order statistics。
Distribution processes of the fractional ARMA type, mixing properties
Distribution processes the fractional ARMA type mixing properties
2009/9/22
In this Pa per we firstly study f, the inverse Laplace transform of F(s) = n,=(,s - 0 3 . The distribution f is then used to
define a family of linear distribution processes. This family generalizes
...
Properties of Green function of symmetric stable processes
Properties of Green function symmetric stable processes
2009/9/22
We study the Green function G,(x, y) of symmetric
w-stable processes in for an open set D (0 < a < 2, d 3 3). Our main
result gives the upper and the lower bound estimates of G,(x, y) for
a bounded...
On some properties of one-dimensional diffusion processes on an interval
some properties one-dimensional diffusion processes interval
2009/9/22
Some equations are obtained for the moments of the
first passage time of a one-dimensional time-homogeneous diffusion
process, through each of two accessible boundaries cr and fl, given that
the pr...
Inferring Climate System Properties Using a Computer Model
model calibration climate change climate sensitivity Bayesian methods
2009/9/22
A method is presented to estimate the probability distributions of
climate system properties based on a hierarchical Bayesian model. At the base
of the model, we use simulations of a climate model i...
Almost sure properties of weighted vectorial martingales transforms with applications to prediction for linear regression models
least squares estimators cumulative prediction and estimation Linear regression models
2009/9/21
We establish new almost sure properties for powers of
weighted martingale transbrms. It allows us to deduce usefuI asymptotic
results for cumulative prediction and estimation errors associated
