Forecasting periode 1
Les 1: Tijdsreeksen (lineaire regressie)
Voorspellen van toekomst op basis van het verleden door middel van tijdsreeksen (lineaire regressie)

Componenten van tijdsreeks:

 Trend (T): gelijkblijvend, dalend, stijgend, exponentieel
 Conjunctuurcomponent (C): economische cyclus (lange termijn)
 Seizoencomponent (S): seizoenen (zonnebrillen, ski’s), dagpatroon (watergebruik
huishoudens)
 Toevallige component (E): onregelmatige veranderingen  verklaarbaar (verkoop van
paraplu’s) of onverklaarbaar

Doel van tijdsreeks:

 Beeld vormen van een systematisch patroon in reeks gegevens uit het verleden
Bv: door CBS bepalen trend- en seizoenpatroon in werkloosheidcijfers

 Op basis van gegevens uit het verleden korte-termijnvoorspellingen doen voor de
toekomst
Bv: Voorspellen van de vraag naar producten om de productie daarmee aan te sturen


Trendlijn berekenen d.m.v. lineaire regressie:

! Excel doet dit automatisch

 Trendlijn: Y = a + bx

 Methode 1:
MAD = Mean Absolute Deviation = gemiddelde absolute afwijking

 Methode 2: (vaker gebruikt)
MSE = Mean Square Error = gemiddelde kwadratische afwijking

 a & b berekenen:




Ȳ = gemiddelde van alle Y-waarden
X̄ = gemiddelde van alle X-waarden = gemiddelde van alle X-waarden
