Inconsistency of the MLE for the joint distribution of interval censored survival times and continuous marks

, 2008
This paper considers the nonparametric maximum likelihood estimator (MLE) for the joint distribution function of an interval censored survival time and a continuous mark variable. We provide a new explicit formula for the MLE in this problem. We use this

Fixed-domain asymptotic properties of tapered maximum likelihood estimators

, 2009
When the spatial sample size is extremely large, which occurs in many environmental and ecological studies, operations on the large covariance matrix are a numerical challenge.

Total positivity in exponential families with application to binary variables

, 2020
We study exponential families of distributions that are multivariate totally positive of order 2 (MTP2), show that these are convex exponential families, and derive conditions for existence of the MLE.

Nonparametric estimation of a convex bathtub-shaped hazard function

, 2010
In this paper, we study the nonparametric maximum likelihood estimator (MLE) of a convex hazard function. We show that the MLE is consistent and converges at a local rate of $n^{2/5}$ at points $x_0$ where the true hazard function is positive and ...

Statistical inference for zero-and-one-inflated poisson models

Statistical Theory and Related Fields, 2017
In this paper, a zero-and-one-inflated Poisson (ZOIP) model is studied. The maximum likelihood estimation and the Bayesian estimation of the model parameters are obtained based on data augmentation method.
