wine: Proton Nuclear Magnetic Resonance spectra of 40 different wine samples
Description
The original data set consists of Proton Nuclear Magnetic Resonance (NMR) spectra of 40 different wine samples in the spectral region from 6.00ppm to 0.50ppm. This data set corresponds to the region between wavelengths 5.62ppm and 5.37ppm only for which \(t = 397\) measurements are available for each curve. The data has been analyzed in Hubert et al. (2015), see below.
Usage
data(wine)
Arguments
Format
A three dimensional \(t = 397\) by \(n = 40\) by \(p = 1\) array,
with \(t\) the number of observed time points,
\(n\) the number of functional observations
and \(p\) the number of measurements
for every functional observation at every wavelength.
