Data for: Data mean and ratio of absorbance to concentration methods: a novel optimization strategy for near infrared modeling

The public NIR testing data were from the appendix of the published articles [1,2]. [1] R. Zhang, Y.Y. Chen, Z.B. Wang, K.W.

The wavelength range is 1100-2498nm at 2 nm intervals (700 channels). The moisture, oil, protein and starch values for each of the samples is also included. A number of NBS glass standards were also measured on each instrument. The data was originally taken at Cargill. Many thanks for Mike Blackburn for letting us distribute it. ② NIR spectra and octane numbers of 60 gasoline samples NIR: NIR spectra, measured in 2 nm intervals from 900 nm to 1700 nm octane: octane numbers spectra: a dataset array containing variables for NIR and octane公开的近红外光谱（NIR，Near Infrared Spectroscopy）测试数据集源自已发表文献[1,2]的附录。[1] R.
