Code

Individuals are free to use the codes for the purpose academic research, provided it is properly acknowledged. For any other use, permission must first be arranged with the author(s). Unless otherwise specified, the author of the codes is Aurore Delaigle. Please contact me if you find errors in the codes.

Matlab or R Codes for my most recent papers can often be found on the journals' webpages. Otherwise email me for a copy.
Matlab and R codes for computing deconvolution kernel density estimator and errors-in-variable regression estimator (data with measurement errors, errors-in-variables) and data-driven bandwidths. Corrects the numerous errors of the R package "decon", especially for the data-driven bandwidths.

WARNING: These are simplified Matlab codes which do not use Fast Fourier Transform. The codes used in my papers were written in C using FFT, which is faster.

Matlab codes written by Aurore Delaigle: Right click/save as to have correct formatting. Code uses the function outerop :

The above Matlab codes have kindly been converted to R codes by Tianying Wang:

Download R package for deconvolution kernel estimator

We have a deconvolve R package (with Tim Hyndman and Tianying Wang) that is in the last debugging phase:
