Je antwoord is heel duidelijk en volledig. Je uitleg is perfect! De uitleg van het Kolmogorov-Smirnov interval vond ik ook heel goed.

Je uitleg is volledig en ik kan hier niets aan toevoegen.

Ik vind dit goed beantwoord. Ik bespreek zowel de raw als de cumulative periodogram. Bij de cumulative periodogram geef er ik nog wat theoretische uitleg over. Mijn conlusies m.b.t. tot de trend en de seizoenaliteit kloppen.
