the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Volumes of logistic regression models with applications to model selection

Logistic regression models with n observations and q linearly-independent covariates are shown to have Fisher information volumes which are bounded below by π and above by ( n q ) π. This is proved with a novel generalization of the classical theorems of Pythagoras and de Gua, which is of independent interest. The finding that the volume is always finite is new, and it implies that the volume c...

Model Selection in Logistic Regression and Performance of its Predic

Logistic regression studies often have several covariates and asked to cull these covariates to arrive at a parsimonious model. The goal is to maximize predictive power while minimizing the number of covariates in the model. Purposeful selection of covariates does not provide efficient model in case of large number of covariates while mechanical stepwise and best subsets selection procedures st...

Bayesian model selection for logistic regression models with random intercept

Data, collected to model risk of an interesting event, often have a multilevel structure as patients are clustered within larger units, e.g. clinical centers. Risk of the event is usually modeled using a logistic regression model, with a random intercept to control for heterogeneity among clusters. Model specification requires to decide which regressors have a non-negligible effect, and hence, ...

High - Dimensional Ising Model Selection Using 1 - Regularized Logistic Regression

We consider the problem of estimating the graph associated with a binary Ising Markov random field. We describe a method based on 1-regularized logistic regression, in which the neighborhood of any given node is estimated by performing logistic regression subject to an 1-constraint. The method is analyzed under high-dimensional scaling in which both the number of nodes p and maximum neighborhoo...
