INTRODUCTION The objective of this study was to compare the associations of accelerometer-derived total activity counts per day and minutes of bouted moderate to vigorous physical activity (MVPA) with insulin resistance. METHODS The sample included 2,394 adults (aged ≥20 y) from the 2003-2006 National Health and Nutrition Examination Survey. Time spent in MVPA, measured by using 2 cutpoints (...

The past century has seen a steady increase in the need of estimating and predicting complex systems and making (possibly critical) decisions with limited information. Although computers have made possible the numerical evaluation of sophisticated statistical models, these models are still designed by humans because there is currently no known recipe or algorithm for dividing the design of a st...

In this paper, we develop an exact method for computing the minimum coverage probability of Wald interval for estimation of binomial parameters. Similar approach can be used for other type of confidence intervals. 1 Wald Interval Let X be a Bernoulli random variable with distribution Pr{X = 1} = 1−Pr{X = 0} = p ∈ (0, 1). Let X1, · · · ,Xn be i.i.d. random samples of X. Let K = ∑n i=1 Xi. The wi...

Der «IDANE Wald+ Science-Policy Dialogue» ist eine erweiterte Diskussionsplattform zu internationalen waldpolitischen Themen mit spezifischen Beiträgen aus der Schweizer Wissenschaft. Im Dezember 2021 organisierte die Abteilung Wald des Bundesamts für Umwelt (BAFU) erste Sitzung IDANE Wald+. Die zweite findet im Oktober 2022 zum Thema «Wald, Bäume und Partnerschaften» statt. Neben Diskussionspl...

A Wald test with enhanced selectivity capabilities is proposed in homogeneous environments. At the design stage, we assume that the cell under test contains a noise-like interferer in addition to colored noise and possible signal of interest. We show that the Wald test is equivalent to a recently proposed Rao test. We also observe that this Rao/Wald test possesses constant false alarm rate prop...

We introduce an analytical model, the Wald analytical long-distance dispersal (WALD) model, for estimating dispersal kernels of wind-dispersed seeds and their escape probability from the canopy. The model is based on simplifications to well-established three-dimensional Lagrangian stochastic approaches for turbulent scalar transport resulting in a two-parameter Wald (or inverse Gaussian) distri...
