Model selection using mass-nonlocal prior
Shi, Guiling,Lim, Chae Young,Maiti, Tapabrata Elsevier 2019 STATISTICS & PROBABILITY LETTERS - Vol.147 No.-
<P><B>Abstract</B></P> <P>Bayesian variable selection is an active research area. The paper proposes a variable selection technique by taking advantages of two distinctive approaches of Bayesian variable selection, namely spike and slab prior and nonlocal prior. Contrary to the local priors, nonlocal priors put zero mass at null values of the parameters. The proposed method uses posterior median as the parameter estimates and asymptotic consistency is established. The Bayesian implementation is proposed via Gibbs sampling. The full conditional distributions are provided. Extensive numerical study indicates superiority of the proposed procedure compared to its competitors. Most importantly, the procedure works well in low signal situation which is not the case in general.</P>
Bayesian model selection for generalized linear models using non-local priors
Shi, Guiling,Lim, Chae Young,Maiti, Tapabrata Elsevier 2019 Computational statistics & data analysis Vol.133 No.-
<P><B>Abstract</B></P> <P>Variable selection is currently an important research topic under both frequentist and Bayesian framework. While most developments in Bayesian model selection literature are based on a local prior on regression parameters, a nonlocal prior for model selection can be also used. In this article, we extend nonlocal prior approach to logistic regression and to generalized linear models. Laplace approximation is used in implementation to avoid integration in the likelihood. A convergence rate is derived under some regularity conditions. The selection based on a nonlocal prior eliminates unnecessary variables and recommends a simple model. The method is validated by simulation study and illustrated by a real data example.</P>

본 증례에서는 임파구성 뇌하수체염으로 의심되었던 뇌하수체 종괴가 경과관찰 및 스테로이드 치료에도 반응이 없어 이후 시상상부 배아종으로 확진된 증례이다. 임파구성 뇌하수체염은 시야결손의 비교적 드문 원인질환이기도 하나, 조직검사를 시행한 부위에 따라 조직학적으로 다른 종양과 감별이 어려운 경우도 있다. 본 증례는 이러한 관점에서 매우 희귀한 경우이며 이에 대한 올바른 진단과 병인, 향후 치료에 대해 생각할 수 있는 계기를 삼고자 본 증례를 보고하는 바이다. We report here on a case of a 22-year-old girl with a suprasellar mass that was originally diagnosed as lymphocytic hypophysitis, but it eventually turned out to be a germinoma. She initially underwent partial tumor removal and the tissue diagnosis was suggestive of lymphocytic hypophysitis. 46 months later, she presented with a lateral visual field defect and decreased visual acuity of her right eye. The serum and cerebrospinal β-hCG and α-fetoprotein levels were measured. The β-hCG level was elevated in both, whereas the α-fetoprotein level was detectable in neither. The serum anti-pituitary antibody-1 level was negative. She was reoperated and the permanent section biopsies were compatible with pure germinoma. There was no evidence of meningeal metastasis on her whole spine MRI. She was treated with chemotherapy. (Korean J Med 73:210-215, 2007)

This article makes an empirical analysis on influence of R&D investment on corporate performance under different nature of controlling stake by applying multivariate regression analysis and ordinary least square and taking China A-share listed companies as samples. The study finds that for the whole sample enterprises and non-state-controlled enterprises, current and last R&D investment have significant positive influence on corporate performance; for state-controlled enterprises, current and last R&D investment have positive influence on corporate performance but not significant.
