Data are abundant, quantitative information about the state of society and wider world is around us more than ever. Paradoxically, recent trends in public discourse point towards a post-factual that seems content to ignore or misrepresent empirical evidence. As statistics educators we challenged promote understanding society. In order re-root debate be based on facts instead emotions evidence-based policy decisions, education needs embrace two areas widely neglected secondary tertiary...
Children typically learn basic numerical and arithmetic principles using finger-based representations. However, whether or not reliance on representations is beneficial detrimental the subject of an ongoing debate between researchers in neurocognition mathematics education. From neurocognitive perspective, finger counting provides multisensory input, which conveys both cardinal ordinal aspects numbers. Recent data indicate that children with good show better skills training gnosis, "finger...
A pandemic poses particular challenges to decision-making because of the need continuously adapt decisions rapidly changing evidence and available data. For example, which countermeasures are appropriate at a stage pandemic? How can severity be measured? What is effect vaccination in population groups should vaccinated first? The process starts with data collection modeling continues dissemination results subsequent taken. goal this paper give an overview provide recommendations for...
Given data from a sample of noisy curves, we consider nonlinear parametric regression model with unknown function. An iterative algorithm for estimating individual parameters as well the function is introduced under assumption certain shape invariance: curves are obtained common by linear transformations axes. Our based on least-squares methods parameter estimation and nonparametric kernel curve estimation. Asymptotic distributions derived estimators estimator application to human growth...
Data science as a practical has been conceived to address tangible problems in science, technology and society. Educating students data goes beyond teaching about algorithms, skills of manipulating sets, selecting applying appropriate analyses, creating interpreting visual representations data. It also involves raising critical understanding how are produced they can be used for particular purposes, including the role context emphasizes developing an awareness ethics, considering...

Abstract Naive implementations of local polynomial fits and kernel estimators require almost O(n 2) operations. In this article two fast O(n) algorithms for nonparametric fitting are presented. They based on updating normal equations. Numerical stability is guaranteed by controlling ill-conditioned situations small bandwidths data-tuned restarting the procedure. Restarting at every output point results in a moderately but highly stable 7/5) algorithm. Applicability evaluated estimation...
SUMMARY For two and higher dimensional kernel regression, currently available bandwidth selection procedures are based on cross-validation or related penalizing ideas. However, these techniques have been shown to suffer from high sample variability and, in addition, can sometimes be difficult implement when a vector of bandwidths needs selected. In this paper we propose selector an iterative plug-in approach for bivariate regression. It is give satisfactory results quickly computed. Our...
A bandwidth selection rule which proved to be useful and effective for nonparametric kernel regression is modified suitable estimation of a density its derivatives. Various versions the are considered. Theoretical properties derived. simulation study compares finite-sample behavior with that other selectors.
For kernel regression estimation a weighting scheme due to Nadaraya and Watson has been associated with random design, convolution type fixed design. Based on integrated mean square error, none of the estimators is uniformly optimal in either However, weights are minimax optimal. Further advantages this estimator can be seen structure bias.
Zusammenfassung Demokratie lebt von Argumenten, die auf nachweisbaren Fakten basieren. Lebendige Demokratien brauchen gut informierte Bürger, relevante gesellschaftliche Fragen verstehen, diskutieren und sich in öffentliche Entscheidungsprozesse einbringen können. Dieser Aufsatz stellt Erweiterung Statistical Literacy eine Teildisziplin vor, wir Zivilstatistik nennen. konzentriert das Verstehen statistischer Informationen über Gesellschaft, wie sie den Medien, Statistikämtern anderen...
