Synthesis of (E)‐β‐SF5‐Styrenes via a Heck Reaction of in situ Generated Vinylsulfur Pentafluoride†
Chinese Journal of Chemistry, EarlyView.A Heck cross‐coupling reaction between aryl(hetero)iodides and in situ generated vinylsulfur pentafluoride is reported. This reaction provides β‐SF5‐styrenes in one‐step as a single (E)‐stereoisomer and tolerates a broad range of functional groups. Comprehensive Summary The synthesis of (E)‐(1‐alken‐1‐yl)pentafluoro‐λ6‐sulfanes, a valuable class of ...

Canadian Journal of Statistics, EarlyView.Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

Canadian Journal of Statistics, EarlyView.Abstract Intensity–duration–frequency curves are used by a wide range of professionals to manage the risks related to extreme rainfall. In Canada, these curves are produced by Environment and Climate Change Canada on the basis of Gumbel distributions fitted independently for each accumulation period.

A goodness‐of‐fit test for regression models with discrete outcomes
Canadian Journal of Statistics, EarlyView.Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.
