E-collaboration researchers usually employ P values for hypothesis testing, a common practice in a variety of other fields. This is also customary in many methodological contexts, such as analyses of path models with or without latent variables, as well as simpler tests that can be seen as...

Zusammenfassung Der p -Wert wird vielfach als Goldstandard für Inferenzschlüsse angesehen. Zur Validierung statistischer Zusammenhänge hat sich die Konvention herausgebildet, möglichst geringe p -Werte einzufordern und bei Werten unterhalb gewisser Schwellen (z. B. 0,05) von statistisch...

Abstract We extend the inference procedure for the synthetic control method in two ways. First, we propose parametric weights for the p-value that includes the equal weights benchmark of Abadie et al. [ 1 ]. By changing the value of this parameter, we can analyze the sensitivity of the...

This paper designs a visual goodness-of-fit test based on the probability integral transformation of the residuals of an estimated model. We illustrate the method with histograms and correlograms of transformed series for different distributions of disturbances in simulated models. An...

Abstract Distortion functions are employed to define measures of risk. Receiver operating characteristic (ROC) curves are used to describe the performance of parametrized test families in testing a simple null hypothesis against a simple alternative. This paper provides a connection between...

Purpose – The purpose of this paper is statistical analysis for the democracy index data of 167 countries for the period 2006 to 2012 to investigate whether democracy index is progressing day by day? Does democracy make any significant improvement in public life and public trust in political...

Purpose – This paper aims to study the effects of two different types of state skepticism prompts, as well as the effect of the trait of professional skepticism on auditor cognitive performance in a hypothesis-testing task. It examines the effect of a professional skepticism prompt, based on...
