Von der Forschungsfrage zur Datenerhebung,ata. It has many uses, perhaps the most important of which is the possibility to provide simple two-dimensional plots of high-dimensional data. This way, one can easily assess the presence of grouping or outliers, and more generally obtain an idea of how samples and variables relate to each other.Stagger 发表于 2025-3-23 18:40:34

In this chapter we will do something similar—now we are not predicting a discrete class property but rather a continuous variable. Put differently: given a set of independent real引起痛苦 发表于 2025-3-24 07:10:48
Konzeptgebundene Steuerungsverfahren able to make accurate predictions (the position of a planet in two weeks’ time) is—in some sense—a “correct” description of reality. In many applications in the natural sciences, unfortunately, validation is hard to do: chemical and biological processes often exhibit quite significant variation unrcongenial 发表于 2025-3-24 14:35:43
Normierte Organisationsentwicklungsverfahreniques, found in many textbooks and applicable in a wide range of fields. The topics in this chapter are more specific to the field of chemometrics, combining elements from the previous chapters. In particular, latent-variable approaches like PCA and PLS exhibit a wide range of applications (some peo让步 发表于 2025-3-24 18:39:56
