A data set with NIR spectra and octane numbers of 60 gasoline samples. The NIR spectra were measured using diffuse reflectance as log(1/R) from 900 nm to 1700 nm in 2 nm intervals, giving 401 wavelengths. Many thanks to John H. Kalivas.
A data frame with 60 observations on the following 2 variables.
a numeric vector. The octane number.
a matrix with 401 columns. The NIR spectrum.
