Edge effect on the way to the GRAAL - page 11

 
yosuf:
I have a regression model, but have never thought to look into estimating it,
A model without estimation isn't a model, it's a fantasy.
 
Vizard:

The wavelet is messing up too.

This forum attracted me to the 'edge effect' in wavelets. It's a known problem. We fit a model on a sample and then extrapolate it "over the edge of the sample" and it doesn't work there. If we solve the edge effect in wavelets, will we be able to solve the problem of extrapolating the model out of sample?

How do you solve it?

Once again: this is the fundamental problem of the wavelet. That is, if you "solve" it, it won't be a wavelet at all.

Pity. So it's nothing more than smoothing.

The point is that it's initially a bit absurd to analyse only onlk

What else? Rumours, news?

Why not? News has a lot to do with it. Trends often break, for example.

What's more - 70% of the "important news" is just numbers. Changes in macroeconomic indicators.

Joke's on you
 
faa1947:
You're kidding.

I'm kind of at a loss as to what to say.

But actually, no. I'm not joking.

If you pull out, for example, the calendar for last year, break it down into machine-readable form, manually throw out all sorts of holidays and stuff, and overlay it on the chart, you'll see a lot of interesting things.

There is a science of measuring economic data. And there is shamanism with shamanism.

And then there are the nonsensical phrases. Meaningless in their purported meaningfulness.

What were you trying to say?
