I have learnt forecasting on job. Yous hould know your maths, you should be analytical i.e converting data into informatiion into intelligence.
Everyone does forecasting of events at some point or other in every day life.
I would recommend you to get a good understanding of jargons such as "trending", "seasonality", "peaks", "troughs", "weighted averages", "regression".
There are many courses on offer on internet as well, but I believe OJT is the best.
Let me know if you want to know more. |
