Semiparametric Estimation of the Distribution of Episodically Consumed Foods Measured With Error

Felix Camirand Lemyre, Raymond J Carroll, Aurore Delaigle

Journal article  |  2020  |  JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION

Dietary data collected from 24-hour dietary recalls are observed with significant measurement errors. In the nonparametric curve e..

Estimating the Covariance of Fragmented and Other Related Types of Functional Data

Aurore Delaigle, Peter Hall, Wei Huang, Alois Kneip

Journal article  |  2020  |  JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION

We consider the problem of estimating the covariance function of functional data which are only observed on a subset of their doma..

Nonparametric density estimation for intentionally corrupted functional data

A Delaigle, A Meister

Journal article  |  2020  |  Statistica Sinica

We consider statistical models where functional data are artificially contaminated by independent Wiener processes in order to sat..

Clustering functional data into groups by using projections

Aurore Delaigle, Peter Hall, Pham Tung

Journal article  |  2019  |  JOURNAL OF THE ROYAL STATISTICAL SOCIETY SERIES B-STATISTICAL METHODOLOGY

We show that, in the functional data context, by appropriately exploiting the functional nature of the data, it is possible to clu..

Estimation of conditional prevalence from group testing data with missing covariates

Aurore Delaigle, Wei Huang, Shaoke Lei

Journal article  |  2019  |  Journal of the American Statistical Association

We consider estimating the conditional prevalence of a disease from data pooled according to the group testing mechanism. Consiste..

Nonparametric Estimation of the Size and Waiting Time Distributions of Pulsar Glitches

A frequency domain analysis of the error distribution from noisy high-frequency data

Jinyuan Chang, Aurore Delaigle, Peter Hall, Chengyong Tang

Journal article  |  2018  |  BIOMETRIKA

Data observed at a high sampling frequency are typically assumed to be an additive composite of a relatively slow-varying continuo..

Approximating fragmented functional data by segments of Markov chains

A Delaigle, P Hall

Journal article  |  2016  |  BIOMETRIKA

We consider curve extension and linear prediction for functional data observed only on a part of their domain, in the form of frag..

NONPARAMETRIC COVARIATE-ADJUSTED REGRESSION

Aurore Delaigle, Peter Hall, Wen-Xin Zhou

Journal article  |  2016  |  ANNALS OF STATISTICS
