Aggregated estimating equation estimation [PDF]

open access: yesStatistics and Its Interface, 2011
Motivated by the recent active research on online analytical processing (OLAP), we develop a computation and storage efficient algorithm for estimating equation (EE) estimation in massive data sets using a “divide-and-conquer” strategy. In each partition of the data set, we compress the raw data into some low dimensional statistics and then discard the

On some composite Kies families: distributional properties and saturation in Hausdorff sense

open access: yesModern Stochastics: Theory and Applications, 2023
The stochastic literature contains several extensions of the exponential distribution which increase its applicability and flexibility. In the present article, some properties of a new power modified exponential family with an original Kies correction ...

Confidence Intervals for Stereological Estimators with Infinite Variance [PDF]

open access: yes, 1981
A statistical estimator is discussed for using two-dimensional electron-microscope data to estimate NV, the number of organelles per unit volume. Under general assumptions, the estimator is shown to be the unique unbiased estimator of NV.

Variance Estimation in a Random Coefficients Model [PDF]

open access: yes, 2006
This papers describes an estimator for a standard state-space model with coefficients generated by a random walk that is statistically superior to the Kalman filter as applied to this particular class of models.

Piecewise convex function estimation: pilot estimators [PDF]

open access: yesThe Annals of Statistics, 1997
Given noisy data, function estimation is considered when the unknown function is known a priori to consist of a small number of regions where the function is either convex or concave. When the number of regions is unknown, the model selection problem is to determine the number of convexity change points.

Hazard models with varying coefficients for multivariate failure time data [PDF]

open access: yes, 2007
Statistical estimation and inference for marginal hazard models with varying coefficients for multivariate failure time data are important subjects in survival analysis.

An improved estimator for non-Gaussianity in cosmic microwave background observations [PDF]

open access: yes, 2012
An improved estimator for the amplitude fnl of local-type non-Gaussianity from the cosmic microwave background (CMB) bispectrum is discussed. The standard estimator is constructed to be optimal in the zero-signal (i.e., Gaussian) limit.

Silhouette estimation

open access: yesJournal of the Optical Society of America A, 2014
Silhouettes arise in a variety of imaging scenarios. Pristine silhouettes are often degraded via blurring, detector sampling, and detector noise. We present a maximum a posteriori estimator for the restoration of parameterized facial silhouettes. Extreme dealiasing and dramatic superresolution, well beyond the diffraction limit, are demonstrated ...

Development and testing of a soot particle concentration estimator using Lagrangian post-processing

open access: yesEngineering Applications of Computational Fluid Mechanics, 2018
Soot emissions from combustion devices are known to have harmful effects on the environment and human health. As the transportation industry continues to expand, the development of techniques to reduce soot emissions remains a significant goal of ...
