cellwise-outliers-detection-in-optical-emission-spectroscopy

Rowwise outliers detection is the most common action most spectroscopists/chemometricians take to deal with discordant reading. However, an alternative method such as MacroPCA enables to account for cellwise outliers in spectroscopic analysis.
