The benefits of combining multiple sources
Four models, one combined forecast – for better accuracy.
Less noise, fewer misses
By comparing multiple sources, we identify deviations and present the most likely forecast.

The right model, the right place
Each institute has a home turf – we weight their models accordingly.
