So predicting x for given y is a statistical heressy!! I mean you can still calculate x', but don't write home about it!

Strictly speaking, it is not a forecast of x, but it answers the question: What x will result in a forecast of a given y?

I got what you mean. Just so I can understand the mathematics behind that, in what way is this method not a forecast?

Thanks
