Bij Q1 werden de juiste berekeningen gemaakt. Er was wel onvoldoende uitleg te lezen. Bij de partial correlation word bv bij de correlatie van x met y, de invloed van z weggezuiverd. De correlatie van 2 kan een heel vertekend beeld geven omdat ze onder invloed staan van een derde, bij de partial correlation word deze invloed echter weggezuiverd zodat we een juist beeld krijgen van de correlatie van x en y. Bij deze tijdreeksen zie je goed het verschil wanneer een 3de component word weggezuiverd. Wanneer we z en x wegzuiveren is het verschil het grootst.
Q2 vertoonde een error en er werd geen uitleg gegeven.
Q3, Q4, Q5 werden niet opgelost.

De uitleg van Romina, hierboven is volledig correct. De juiste berekening werden gemaakt en haar opmerkingen zijn terecht.
