Raman.test: Raman Spectroscopy on Fish Oil

Description

This data set contains Raman spectra for 15 salmon oil samples extracted from farmed salmon, Salmo salar. The Iodine number, which is connected to the degree of unsaturation in the fatty acids, is reported.

Usage

Raman.test

Format

A data frame with 15 observations (rows) and 2264 variables (columns).

	Column name	Data type	Description	Values
[,1]	Iodine_number	numeric	Indicator for unsaturation in the fatty acids	(154.4021 - 168.3116)
[,2:2264]	RSdata1...RSdata2263	numeric	Raman spectroscopy data	(-0.004085908 - 0.107787)

Details

The wavelengths used in the Raman spectroscopy were -20 cm^{-1} – 3450 cm^{-1}. Wavelengths before 790 cm^{-1} and after 3050 cm^{-1} are not included in this data.

The Raman data with a total of 45 observations was split into a training data with 30 observations and this test data set with the remaining 15 observations.
