Research

Nason is best known for his work in the area of time series analysis, especially wavelet
Wavelet
A wavelet is a wave-like oscillation with an amplitude that starts out at zero, increases, and then decreases back to zero. It can typically be visualized as a "brief oscillation" like one might see recorded by a seismograph or heart monitor. Generally, wavelets are purposefully crafted to have...

 approaches.

Book

Nason's book Wavelet Methods in Statistics with R (Springer, 2008, ISBN 978-0-387-75960-9) describes methods of performing statistical analysis with wavelets using the R

Shrinkage (statistics)
In statistics, shrinkage has two meanings:*In relation to the general observation that, in regression analysis, a fitted relationship appears to perform less well on a new data set than on the data set used for fitting. In particular the value of the coefficient of determination 'shrinks'...

Smoothing
In statistics and image processing, to smooth a data set is to create an approximating function that attempts to capture important patterns in the data, while leaving out noise or other fine-scale structures/rapid phenomena. Many different algorithms are used in smoothing...
