Single Index Models with Mixeddiscrete
نویسنده
چکیده
A single index model is studied with binary response and mixed explanatory variables represented by a continuous part and one binary discrete variable. The model leads to a two sample semiparametric problem with a shift parameter related to this discrete variable. The minimal Fisher information for the shift parameter is found in a class of nonparametric link functions. Two root-n consistent estimators of the shift parameter are proposed, based on a comparison of the shift in link functions in the "vertical" and the "horizontal" direction. The limiting variances of these estimators show that properly weighted "horizontal" shifts guarantee asymptotic eeciency. Some simulations show the applicability of these methods.

Single-phase Near-well Permeability Upscaling and Productivity Index Calculation Methods
Reservoir models with many grid blocks suffer from long run time; it is hence important to deliberate a method to remedy this drawback. Usual upscaling methods are proved to fail to reproduce fine grid model behaviors in coarse grid models in well proximity. This is attributed to rapid pressure changes in the near-well region. Standard permeability upscaling methods are limited to systems with ...

Background and objectives: Coronary artery disease (CAD) is associated with negative emotions of anger and stress, which are one of the nonclinical risk factors of the disease. Therefore, evaluation of the effective therapeutic models alleviating the patients’ negative emotions is of paramount importance. This study aimed to examine the effect of mindfulness-based stress reduction (MBSR) on ang...
