Bootstrap Estimation for GEE Models

Estimation of INAR(p) models using bootstrap

In this paper we investigate bootstrap techniques applied to the estimation of the thinning parameters in INAR(p) models. We propose a new bootstrap approach based on sieve bootstrap. The approach is then applied to the Yule-Walker estimator of the thinning parameters. Monte Carlo experiments are carried out to valuate the performance of bootstrap estimator and the superiority of our proposal i...

Bias-corrected GEE estimation and smooth-threshold GEE variable selection for single-index models with clustered data

In this paper, we present a generalized estimating equations based estimation approach and a variable selection procedure for single-index models when the observed data are clustered. Unlike the case of independent observations, bias-correction is necessary when general working correlation matrices are used in the estimating equations. Our variable selection procedure based on smooth-threshold ...

Ranking Accuracy for Logistic-GEE Models

The logistic Generalized Estimating Equations (logisticGEE) models have been extensively used for analyzing clustered binary data. However, assessing the goodness-of-fit and predictability of these models is problematic due to the fact that no likelihood is available and the observations can be correlated within a cluster. In this paper we propose a new measure for estimating the generalization...

Variance Estimation and Construction of Confidence Intervals for GEE Estimator

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
