An empirical likelihood method for quantile regression models with censored data
Sign Up to like & getrecommendations! Published in 2020 at "Metrika"
DOI: 10.1007/s00184-020-00775-1
Abstract: An estimation for censored quantile regression models, which is based on an inverse-censoring-probability weighting method, is studied in this paper, and asymptotic distribution of the parameter vector estimator is obtained. Based on the parameter estimation… read more here.

DOI: 10.1007/s42952-019-00047-3
Abstract: By introducing the notion of “empirical likelihood function of observing sums”, unequally-spaced time series data and longitudinal data generated from Levy processes can be analyzed. Characteristic function is further incorporated to handle the situations where… read more here.

DOI: 10.1007/s42952-020-00065-6
Abstract: In this paper, we focus on the empirical likelihood inference for partially linear single-index errors-in-variables (EV) models when the data are right censored and the censoring indicator is missing at random (MAR). Two bias-corrected empirical… read more here.

DOI: 10.1016/j.jspi.2016.09.008
Abstract: Abstract The scientific literature has addressed widely the theoretical and applied framework based on probability weighted moments (PWMs). PWMs generalize the concept of conventional moments of a probability function. These methods are commonly applied for… read more here.

DOI: 10.1080/01966324.2020.1837042
Abstract: Abstract Longitudinal data with a large number of covariates have become common in many applications such as epidemiology, clinical research, and therapeutic evaluation. The identification of a sub-model that adequately represents the data are necessary… read more here.

DOI: 10.1080/03610926.2016.1218027
Abstract: ABSTRACT In this article, we consider statistical inference for longitudinal partial linear models when the response variable is sometimes missing with missingness probability depending on the covariate that is measured with error. A generalized empirical… read more here.
