Nonparametric Inference for the Proportionality Function in the Random Censorship Model
نویسندگان
چکیده
Censorship in the random censorship model is described by a pro-portionality function (t), where (t) is a function of the survival function S T of the lifetimes, and the survival function S C of the censoring times. An estimator of (t) is proposed and asymptotic properties of the estimator are ascertained. A conndence band for (t) using the bootstrap is derived. We also develop a bootstrap test of H 0 :(t)=, where the constant value of is unspeciied. The results are applied to an actual dataset.

Linear Wavelet-Based Estimation for Derivative of a Density under Random Censorship
In this paper we consider estimation of the derivative of a density based on wavelets methods using randomly right censored data. We extend the results regarding the asymptotic convergence rates due to Prakasa Rao (1996) and Chaubey et al. (2008) under random censorship model. Our treatment is facilitated by results of Stute (1995) and Li (2003) that enable us in demonstrating that the same con...
متن کاملNonparametric Estimation of Spatial Risk for a Mean Nonstationary Random Field}
The common methods for spatial risk estimation are investigated for a stationary random field. Because of simplifying, lets distribution is known, and parametric variogram for the random field are considered. In this paper, we study a nonparametric spatial method for spatial risk. In this method, we model the random field trend by a local linear estimator, and through bias-corrected residuals, ...
متن کاملWavelets for Nonparametric Stochastic Regression with Pairwise Negative Quadrant Dependent Random Variables
We propose a wavelet based stochastic regression function estimator for the estimation of the regression function for a sequence of pairwise negative quadrant dependent random variables with a common one-dimensional probability density function. Some asymptotic properties of the proposed estimator are investigated. It is found that the estimators have similar properties to their counterparts st...
متن کاملInference for the Mean Difference in the Two-Sample Random Censorship Model
Inference for the mean difference in the two-sample random censorship model is an important problem in comparative survival and reliability test studies. This paper develops an adjusted empirical likelihood inference and a martingale-based bootstrap inference for the mean difference. A nonparametric version of Wilks' theorem for the adjusted empirical likelihood is derived, and the correspondin...
متن کاملEvaluation of Tests for Separability and Symmetry of Spatio-temporal Covariance Function
In recent years, some investigations have been carried out to examine the assumptions like stationarity, symmetry and separability of spatio-temporal covariance function which would considerably simplify fitting a valid covariance model to the data by parametric and nonparametric methods. In this article, assuming a Gaussian random field, we consider the likelihood ratio separability test, a va...
