Here's a method based on the Mahalanobis distance with PCA.]]> https://nirpyresearch.com/outliers-detection-pls-regression-nir-spectroscopy-python/ Sat, 22 Sep 2018 06:57:37 +0000 https://www.idtools.com.au/?p=1424 Not every data point is created equal. In this post we'll show how to perform outliers detection with PLS regression for NIR spectroscopy in Python.]]>
