They developed … WebPython evaluation Open the file ~/devel/STIR-exercises/evaluate_simulation_brain.py in Spyder (obviously adjust the path if you installed the exercises elsewhere). You can do …
WebMultiplicative scatter effects occur when spectra have large variation at only certain wavelengths. These show up as shifts in slope, or “fanning”, in the scatter effects plot. Some pre-processing methods that can remove multiplicative effects are the multiplicative scatter correction (MSC) and the standard normal variate.
