Seems ok overall.
I would have put LaDG PS5 > PS4 despite the big gap in COMG sales

EDIT : pretty good forecasts

First time seeing this thread. Pretty interesting stuff. I believe SMRPG, Momotaro and HL will all be underestimates once again. P5T should be fine, I think. Can't wait to see the results.
 
I wonder if we could develop a "cumulative" predictive tool matching also Amazon actual sales for predictions
That is exactly what I want to. I have different possibilités, but my favorite for the moment is :
-comg predictions with a model
-Amazon prediction with Another model
- a third model that should decide which model to use depending on the game caracteristics

The reason why I go for that, is that forecast quality depends in the game caracteristics (and may vary from a model to another). For example, PS5 games are already quite well predicted by my current Amazon model. Plus as I use nichebarrier Amazon data, i only have monthly data (which is already nice, tks to him for his work). But, that means I may have a lot of missing days, depending on the release date in the game. That is also an information that is useful to decide which model to use.

Another solution would be to combine both model predictions (e.g. With random Forest frame work).

If you have ideas, do not hesitate.:)

Anyway, we should wait to have Amazon more data. But I will probably propose a first hybrid model by the beginning of 2024:)

EDIT : big fail ^^

Hello !
For 2024, I introduce a new model, based on monthly Amazon sales (from nichebarrier.com, thanks). We only have data from august 2023 for this one, but it already may provide some relevant info. Thus, I will post predictions of both models for a while, before trying to select the best one or to combine both.
Note that, as the Amazon sales are monthly sales, so if a game releases by the end of the month, it may be more difficult to predict.
We have 2 new releases this week, both scoring very low at COMG.

OO awesome!
Also you can check Amazon right now to see what Another Code sold in the past month 2300. Niche Barrier has collated the sales for Another Another up until Dec 29th 2023, so there's some overlap but one can add those together to get 4350. I usually times by 5 since Amazon is around 20% of the the physical market in Japan and that ends with a predication of 21,750 for Another Code. Your multiplier is a lot more generous at around 14.66 (I'm not sure how you are calculating it to be honest so I just divided 30,058 by 2050) which gives 63,781 which seems way too high lol.

Doing the same for The Last of Part II Remastered (Niche Barrier data through to Dec 29th + current Amazon sales X 5) = 8250
Using your multiplier (11.78) = 19,437

I'd be very interest to know how you made the Amazon prediction 🙂. Mine is crude lol. It worked when I used it for Raincode though since COMG was way off for that title.

Hey,
Thanks for the info about de Amazon sales. It will stick to my monthly sales, as it is faster and easier for me.
Concerning your method for multiplier, it seems pretty relevant. On my side, I build a statistical/machine learning model based on the Amazon sales at the end of last month, the number of days that are not included (comparison between the end of last month and the release date) and the caracteristics of the game (console, editor). It provides me an estimator for the multiplier. As we lack of data, this model should improve with time and we should be patients ^^

Thanks for the explanation! Yeah I've just been roughly trying to work out what games would debut at on the Famitsu chart and I wasn't really sure how best to do it so that's what I came up with lol. I had no idea you was working on a method! I look forward to seeing the results. 🙂

Amazon forecasts are usually above the COMG ones. Great difference for LaD PS5, Shiren and Apollo Justice. More close predictions for the others.
Interesting week for sure!

EDIT : quite a decent week, except for Ace Attornay.

Amazon model prediction are completely off this week, with a systematical overestimation. Low Amazon ratio this week but still. Again, be patient, we only have a few months of background for amazon data (vs many years for COMG)
COMG model did pretty good.

The combined model (COMG and Amazon in one model) I am building is improving week after week as well. But for now, it is not performant enough to be part of the comparison (test error of 60% for combined vs 40% for COMG and Amazon)

Once again, amazon predictions are relatively high. Also note that the case Skull and Bones is very particular: the amazon sales are very high (11500) compared to COMG (2) but most of it were probably a long time ago (and may have been canceled since). Depending on the actual sales, I would probably remove S&B from the database.

EDIT 1: I found some bug in my code, which explains such a big overestimation from Amazon model for a few weeks. I have changed this week predictions and decided to reset the competition score between both model.
EDIT 2: MvsDK forecast were far from reality (but the reality was quite surprising^^). I will probably remove MvsDK and S&B from data base
