Application of near infrared spectroscopy to peanut

Discriminant analysis on spectra of near infrared reflectance spectroscopy was successfully used by Karen et al to differentiate vegetable oil types (cottonseed peanut soybean and canola) and to classify unknown oil samples Second derivative spectra of the vegetable oils were subjected to discriminant analysis with four different

In this study single-kernel Fourier transform near-infrared (FT-NIR) spectroscopy with a wavelength range of 1000-2500 nm was used to distinguish viable and nonviable supersweet corn seeds Various preprocessing algorithms coupled with partial least squares discriminant analysis (PLS-DA) were implemented to test the performance of

Detection and Attribution of Multivariate Climate Change

An application of discriminant analysis for the seasonal prediction of storms was presented by DeGaetano et al (2002) We will demonstrate that discriminant analysis is very effective in enhancing the discriminability between climate PDFs and at the same time has the potential to reduce the dimension of the data substantially (cf Hannart 2016)
