Nonparametric variance function estimation with missing data
In this paper a fixed design regression model where the errors follow a strictly stationary process is considered. In this model the conditional mean function and the conditional variance function are unknown curves. Correlated errors when observations are missing in the response variable are assumed. Four nonparametric estimators of the conditional variance function based on local polynomial f...
متن کاملKernel Estimation of Rate Function for Recurrent Event Data.
Recurrent event data are largely characterized by the rate function but smoothing techniques for estimating the rate function have never been rigorously developed or studied in statistical literature. This paper considers the moment and least squares methods for estimating the rate function from recurrent event data. With an independent censoring assumption on the recurrent event process, we st...
متن کاملNonparametric modeling of the gap time in recurrent event data.
Recurrent event data arise in many biomedical and engineering studies when failure events can occur repeatedly over time for each study subject. In this article, we are interested in nonparametric estimation of the hazard function for gap time. A penalized likelihood model is proposed to estimate the hazard as a function of both gap time and covariate. Method for smoothing parameter selection i...
متن کاملNonparametric Estimation of the Intensity Function of a Recurrent Event Process
In this paper, we consider estimating the intensity of a recurrent event process observed under a standard censoring scheme. We first propose a collection of kernel estimators for which we provide MSE and MISE bounds. We then describe and study an adaptive procedure of bandwidth selection, in the spirit of Goldenshluger and Lepski (2011), and prove an oracle type bound for both the MSE and the ...
متن کاملConcepts and Tests for Trend in Recurrent Event Processes
Interest in the presence and nature of trend arises frequently in science, public health, technology, and many other areas. In this ar- ticle we discuss the notion of trend in the context of recurrent event processes. We discuss different frameworks within which one can inves- tigate trend and consider various ways in which trends may be manifest. Tests for trend are discussed in detail and t...
