Estimation of the Distribution of Episodically Consumed Foods Measured with Error
Date: Thursday, 21 October 2021
Time: 10 am - 11 am
Speaker: Professor Aurore Delaigle
Abstract:
Dietary data collected from 24-hour dietary recalls are observed with significant measurement errors. In the nonparametric curve estimation literature, a lot of effort has been devoted to designing methods that are consistent under contamination by noise. However, some foods such as alcohol or fruits are consumed only episodically, and may not be consumed during the day when the 24-hour recall is administered. Existing nonparametric methods cannot deal with those so-called excess. We present new semiparametric estimators of the distribution of such episodically consumed food data.
