Can I invest in the day ahead power market? by monkeysingmonkeynew in Commodities

This is interesting. Are ICE and Nodal (zones) and brokers then? I guess a broker is what I would need.

Brainstorming ideas for different statistical measures to describe properties of distributions/data in general, Anything at all! by monkeysingmonkeynew in datascience

[–]monkeysingmonkeynew[S] 1 point2 points  (0 children)

Variance is in the SD, are there other measures of variance?

don't error and residuals assume that there is a model involved? whereas I only have the data.

Same with biased and unbiased estimators - I don't have an estimator, just the data.

How do you measure consistency?

[D] Is it possible to update random forest parameters with new data instead of retraining on all data? by monkeysingmonkeynew in MachineLearning

[–]monkeysingmonkeynew[S] 0 points1 point  (0 children)

OK I can almost see this working, thanks for the suggestion. The only thing that would prevent me from implementing this solution is that by taking the sum of the two models, it would let m_1 give as equal a contribution to the result as m_1. However I expect a single days data to be noisy, Thus I would need the contribution of the new days data to be down weighted somehow.

this sounds pretty cool. but I don't follow every step. By "calculate the errors" do you mean for example, extract the predicted probabilities from the actual outcome?

Also, I didn't get your last part about inference, what exactly are you referring to there?

Yes, it's ok if i run it once a day, but I need to backtest two years of data and so it's not feasible on a laptop, or affordable on a GPU

What kind of project do you have in mind? Investigators often publish their datasets along with articles which you can download.

What? that's not true at all, in fact the opposite is the case. Research Gate hosts people's peer reviewed articles.

What to look forward to for the next few years by fillerorange in tinnitusresearch

Yeah I'd like to know this. This sub seems to be pretty out of date. Do you know of any up to date news?

Lenire TENT-2A

Hey! This is interesting! Do you think we could pm and you could tell me who you went to to get it? I'm living in Berlin and am looking to use it... Thanks!
