Yuval,
My point was not about how to best calculate a t-test.
I do not think that I misunderstood that Marco wants to bring machine learning to the platform.
He said he is is committed recently in the forum. I believe he has purchased new servers, It has taken time and probably time means money with regard to the work of his machine learning expert and the hard work of programmers, His time and effort have value too. I believe him and I support his efforts. Am I wrong that he is serious about wanting machine learning to succeed at P123?
We are, in fact, talking about calculating t-scores and p-values in a spreadsheet at P123. That is a observable fact. Also we have talked about calculating the Information ratio in a spreadsheet, Spearman’s rank correlation, in a spreadsheet……There are few statistical metrics that have not been requested as features that, if you want to use them, you can….calculate it in a spreadsheet. Am I wrong about that?
Is that common for a site that calls itself a machine learning site?
Some people have real problems with the metrics (non duckruck who just finds it easier). It is now something ChatGPT might be able to help P123 members with. BTW, I actually made the point that these feature requests may be less needed which would be a positive point for P123.
More importantly, any machine learning method will require metrics that are………(you guessed it) not calculated in a spreadsheet. I think that is true, right?
ChatGPT just happens to be available now. There is nothing P123 did to make these metrics more available or easier for members.
Riccardo said this in the forum:
I do not mean to put words into you mouth. Maybe you can tell us which of these you are exited about.
I appreciate you were being humble with this and I actually appreciate it:
But I am guessing regression might not be one of the methods you support and some of what I have said is based on that. So is it neural nets you will support–if it is not regression–when P123 releases its AI/ML? Support Vector Machines, perhaps?
My post was not about how to do t-tests. And I do not question Marco’s commitment. Just tell us you support machine learning at P123 and we can move on.
Best regards,
Jim
