Model Based Bootstrap Methods for Interval Censored Data
Bodhisattva Sen, Gongjun Xu
We investigate the performance of model based bootstrap methods for constructing point-wise confidence intervals around the survival function with interval censored data. We show t…
Testing against a linear regression model using ideas from shape-restricted estimation
Bodhisattva Sen, Mary Meyer
A formal likelihood ratio hypothesis test for the validity of a parametric regression function is proposed, using a large-dimensional, nonparametric double cone alternative. For ex…
Bootstrapping a Change-Point Cox Model for Survival Data
Gongjun Xu, Bodhisattva Sen, Zhiliang Ying
This paper investigates the (in)-consistency of various bootstrap methods for making inference on a change-point in time in the Cox model with right censored survival data. A crite…
On Testing Independence and Goodness-of-fit in Linear Models
Arnab Sen, Bodhisattva Sen
We consider a linear regression model and propose an omnibus test to simultaneously check the assumption of independence between the error and the predictor variables, and the good…
