Wild bootstrap tests for IV regression [PDF]

open access: yes
We propose a wild bootstrap procedure for linear regression models estimated by instrumental variables. Like other bootstrap procedures that we have proposed elsewhere, it uses efficient estimates of the reduced-form equation(s).

A Robust Confidence Interval for Location for Symmetric, Long-Tailed Distributions [PDF]

open access: yesProceedings of the National Academy of Sciences, 1973
A procedure called the wave-interval is presented for obtaining a 95% confidence interval for the center (mean, median) of a symmetric distribution that is not only highly efficient when the data have a Normal distribution but also performs well when some or all of the data come from a long-tailed distribution such as the Cauchy.

Condition monitoring for the quadruple water tank system using H-infinity Kalman Filtering

open access: yesMATEC Web of Conferences, 2018
The problem of statistical fault diagnosis for the quadruple watertanks system is examined. The solution of the fault diagnosis problem for the dynamic model of the four-water tanks system is a non-trivial case, due to nonlinearities and the system’s ...

Late Holocene climatic variability in Subarctic Canada: Insights from a high-resolution lake record from the central Northwest Territories.

open access: yesPLoS ONE, 2018
We examined late Holocene (ca. 3300 yr BP to present-day) climate variability in the central Northwest Territories (Canadian Subarctic) using a diatom and sedimentological record from Danny's Lake (63.48ºN, 112.54ºW), located 40 km southwest of the ...

Fast Universal Algorithms for Robustness Analysis [PDF]

open access: yespublished in book ``Probabilistic and Randomized Methods for Design under Uncertainty, pp. 415-431, edited by G. Calafiore and F. Dabbene, Springer Verlag, 2006, 2008
In this paper, we develop efficient randomized algorithms for estimating probabilistic robustness margin and constructing robustness degradation curve for uncertain dynamic systems. One remarkable feature of these algorithms is their universal applicability to robustness analysis problems with arbitrary robustness requirements and uncertainty bounding ...

Risk of Hepatotoxicity in Patients With Gout Treated With Febuxostat or Benzbromarone: A Propensity Score–Matched Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective The objective of this study was to evaluate and compare the risk of hepatotoxicity associated with the use of febuxostat and benzbromarone in patients with gout. Methods New users of febuxostat or benzbromarone with monitoring of liver function at least three times in a year after initiation of the study drugs were identified from an ...

Robust Small Sample Accurate Inference in Moment Condition Models [PDF]

open access: yes
Procedures based on the Generalized Method of Moments (GMM) (Hansen, 1982) are basic tools in modern econometrics. In most cases, the theory available for making inference with these procedures is based on first order asymptotic theory.

Using Bootstrapping to Determine Artificial Neural Network Confidence Intervals—Case Study of Particleboard Internal Bond Determined from Production Data

open access: yesApplied Sciences
Tensile strength perpendicular to the plane of the board (also known as the Internal Bond—IB), determined in accordance with standard EN 319, is one of the most critical properties in particleboard quality control.

CONTINA: Confidence Interval for Traffic Demand Prediction with Coverage Guarantee [PDF]

open access: yesarXiv
Accurate short-term traffic demand prediction is critical for the operation of traffic systems. Besides point estimation, the confidence interval of the prediction is also of great importance. Many models for traffic operations, such as shared bike rebalancing and taxi dispatching, take into account the uncertainty of future demand and require ...

Colchicine Concentrations and Relationship With Colchicine Efficacy and Adverse Events: Post Hoc Analysis of a Randomized Clinical Trial of Colchicine for Gout Flare Prophylaxis

open access: yesArthritis Care &Research, EarlyView.
Objective Our objective was to examine the relationship between colchicine plasma concentrations and clinical and demographic factors and to determine the relationship between colchicine concentrations and colchicine efficacy and colchicine‐specific adverse events.
