Shootout NIR data

Description

NIR data from 654 tablets, measured at two different instruments. The data have been divided in training, test and validation sets.

Usage

1

Format

Variable shootout is a list containing spectral data of tablets, measured on two instruments, as well as response variables.

Details

For every tablet, three reponse variables are measured: the amount of active ingredient (nominally 200 mg/tablet), the weight and the hardness. Typically, one wants to estimate the amount of active ingredient from the NIR spectra, a straightforward multivariate calibration problem. The goal of the shootout competition was to find the optimal way to transfer a calibration model of the first instrument to the second.
