A new nonparametric estimator of the local Hurst function of a multifractional Gaussian process based on the increment ratio (IR) statistic is defined. In a general frame, the point-wise and uniform weak and strong consistency and a multidimensional central limit theorem for this estimator are...

Aufgrund ihrer Nähe zum Konzept kontrafaktischer Kausalität haben nichtparametrische Matchingverfahren in der neueren statistischen und ökonometrischen Literatur zur Kausalanalyse an Bedeutung gewonnen. Vor diesem Hintergrund führt der Beitrag das Rubin Causal Model (RCM) in die...

Having close linkages with the counterfactual concept of causality, nonparametric matching estimators have recently gained in popularity in the statistical and econometric literature on causal analysis. Introducing key concepts of the Rubin causal model (RCM), the paper discusses the...
