look for yourself

I'll give you 10 reasons, and none of them will be statistically significant.

Same thing with your calculations so far.

Seen several interpretations of the term.

Interpretations from the chattering classes.

Quite specifically.

There is a file A, for example, of size 2000

From it we get file train of size 1500 by generating a random sample by sample()

ind <- sample( 2000, 1500); ind

[1] 830 1537 607 651 1244 211 1033 767 452 744 533 1784 1791 1470 846 1448 354 1304 1274 1901 1991 220 1069 341 730

So it turns out that a professional trader is a trader who earns money by trading on the market and lives from it.

I know those who meet this definition, you are mistaken with their perception of others.

And professionals look at them both with pity and condescension and quietly say to themselves: when will you b...bleep think of changing the concept, not the scenery....

Same with your calculations so far.

Who told you I have one reason and not 1,000?

You made it up, you believed it, you made fun of yourself.... ))

Those who fit that definition know you are wrong about their perception of those around them.

It's quite possible, I won't argue, it was a joke post, not a statement....

Strange, you claimed 10 min ago that you don't know professionals, and now suddenly you do).

Quite specifically.

You have failed to explain it clearly. train and test, of course, do not overlap.


Here is a computational process (it is called training, optimisation - it doesn't matter). Are both samples involved in this process?

Well, you just blurted something out again, without any proof.

You're not making yourself clear. train and test certainly don't overlap.

The code is not clear?

train is a file on which the model is trained, i.e. a list of patterns is formed, if in a random forest, then about 100 patterns.

test is a file where the algorithm predicts the value of the target variable based on the patterns.
