Data VisualizationFollowing best practice guidelines, visual data inspection should always be the first step of data analysis in order to test the data for plausibility. For this, the PEAXACT Data Inspector offers powerful functions to visualize and explore your data with 2D or 3D graphs, whether you just have a bunch of spectra or a large data table with lots of features.
Data PretreatmentA typical goal of data inspection is to find correlations between spectra and predictive features, because later, for training a model in predicting features from unknown spectra, such correlations are absolutely needed. Often it is possible to emphasize these correlations by means of data pretreatments.
Psssst...Since you made it through the tour so far, let me tell you a little secret: The PEAXACT Data Inspector can be used free of charge, on any computer, for private or commercial use. Just install PEAXACT, start it, and when asked for a license choose the "Free Viewer" license.
