Visualizing Forecast

Your forecast seemed to be off by over 18% on average. Let's visually compare your forecast with the validation data set to see if we can see why. Your workspace has your forecast object forecast_MET_t and validation data set MET_t_valid loaded for you. Don't forget your validation is 22 weeks long!

Instructions

100 XP

Convert the mean of your forecast (forecast$mean) into an xts object using the for_dates object for the time index remembering that your validation data set is 22 weeks long.
Plot your validation data set.
Overlay your forecast (for_MET_t_xts) on top of the validation.
Don't change the plotting options in either to make it easier to see.
