I am analyzing the effect of an unusual event (Z) on demand (Y) , I have used data up to one year after the unusual event ( daily time-series data) , I modeled the event's effect using dummy variables for the period after the event and interacton variables (product of dummy variable and other explanatory variable in the model) , the impact of (Z) on demand was huge and change in the demand pattern and magnitude has occurred after the unusual event, Now i would like to check whether the impact of that unusual event has ended, i collected additional demand data up to 3 years after the event, i would like to ask for your help in doing so, Thank you
This is an intervention case; the unusual event is an intervention. A comparison of the pre-intervention and the post-intervention means may be carried out. If the difference is statistically significant, this is an indication of the significance of the impact of the unusual event. Even after the three years, the post-intervention mean level is still significantly different from the pre-intervention level, there is an impact still. Moreover, an intervention model may be fitted to the data up to the current level. If it is statistically significant the unusual event still has an impact.
