What is "homokedastic"?

Let's think of it as constant variance as opposed to heteroscedasticity, in which the variance has several variants of variability.

Here is the model (regression): EURUSD = 0.999639862102*HP(-1) - 0.0587695175407*HP_D(-1) - 0.426573959137*HP_D(-2)

HP is a Hedrick-Prescott filter. We smooth out the quotient itself and the residue from the filter.

Here is the H1 forecast:

And here is the error of this forecast:

The error peak is 34 pips for the hour mark and it is obviously a random value. Should we trust the forecast with such an error?



Aleksandr Aleksandrovich, do you personally know at least one person who has made at least one forecast decision in his life?

There are no other options. Any TS based on the postulate "history repeats itself" is a forecast. We have found a pattern and we believe that it will repeat and we will make a profit. But the error in making this decision is unknown.

You can't trust a 0.0000001 pip error either... very easy to get with NS...and the smaller the sample, the easier it is to get...

The numbers are nothing - it may be a crooked one ...but it will work...

Yea ... All life is a prediction.

Don't flatter, men. Don't flatter.

We got this.

We've met before.

I agree. I refer to NS as a smoothing model. To work with it you need to test it for stability. Without that, the numbers are nothing and about nothing.

We'll do it ourselves.

Mgya ... All life is a prediction.

I have explained my point of view many times on this forum. I've even written an article.

I will try to publish an article on prognosis. I can't do it without an article as there is too much information to imply

I would say more as a search model...but often the search comes down to a fit...

In principle, any algorithm fits... so the bigger the sample in a model search - the better (for the same error for example)... and you should pay not insignificant attention to it...
