Deconvolution density estimation with heteroscedastic errors using SIMEX
Density estimation deconvolution measurementerrors SIMEX heteroscedasticity
2010/3/18
In many real applications, the distribution of measurement error
could vary with each subject or even with each observation so the errors
are heteroscedastic. In this paper, we propose a fast algori...
We propose two estimators of a monotone spectral density, that
are based on the periodogram. These are the isotonic regression of
the periodogram and the isotonic regression of the log-periodogram.

Flexible Multivariate Density Estimation with Marginal Adaptation
Copula mixture of normals nonparametric stochastic approximation
2010/3/17
Our article addresses the problem of flexibly estimating a multivariate density
while also attempting to estimate its marginals correctly. We do so by proposing
two new estimators that try to captur...
Model selection for density estimation with L2-loss
Density estimation L2-loss model selection estimator selection histograms
2010/4/30
We consider here estimation of an unknown probability density s belonging
to L2(μ) where μ is a probability measure. We have at hand n i.i.d. observations
with density s and use the squared L2-norm ...
Multiscale inference about a density
Exponential inequality modes monotone failure rate multipletest order statistics spacings subexponential increments
2010/4/29
We introduce a multiscale test statistic based on local order
statistics and spacings that provides simultaneous confidence statements
for the existence and location of local increases and decreases...

Density Estimation of Censored Data with Infinite-Order Kernels
Density estimation hazard function estimation infinite-order kernels nonparametric estimation
2010/4/28
Higher-order accurate density estimation under random right censorship is achieved
using kernel estimators from a family of infinite-order kernels. A compatible bandwidth
selection procedure is also...
From e-entropy to KL-entropy：Analysis of minimum information complexity density estimation
Bayesian posterior distribution minimum description length density estimation
2010/4/26
We consider an extension of "-entropy to a KL-divergence based
complexity measure for randomized density estimation methods. Based
on this extension, we develop a general information-theoretical ine...
