Mike is very familiar with the PA model, so it would probably be a good idea to take up his offer and test it there. All going well, it would add to the evidence to present to M@x.

OK, I'll do whatever it takes! Go ahead with whatever you have in mind, Mike!

So what's going on? Is Mike using the system or is he away?

Keep it in our view FC.
At the moment, M@x is very busy with the routine aspects of the site anyway.

Ok, I'll add the algorithm to my website later today (in the evening). Is the code in the first post still valid, or has it been updated/improved in the meantime?

Yes, actually it has been edited numerous times since the first post. My following posts should describe the changes in detail. Umm... I'm not exactly sure how they would "look" in a formula.... I'll see if I can come up with something to make this simpler for you, but I'm going to be out all day so it could take a little time. Unless you know how to incorporate the other stuff. We'll see

Damn I was just typing all this out and FOR SOME REASON MY PAGE CLOSED AND I LOST IT ALL!!!!!!
 AHHH!!! I'm going to type this out in Word so I can save it!! But honestly Mike, I think it would be much easier if you just took a look at the Excel file I have uploaded here Any version of Microsoft Excel from 97-08 should be able to open it. ONLY look at the tab labeled NEW METHOD! The other tabs revolve around the my old method, which isn't as good! The example you're seeing on that tab is King Crimson's Red. If you pan over any of the input fields, I left comment boxes that explain what each one is for. Except for the stuff in the DO NOT EDIT box. That's all the complex stuff... I'm sure you can figure out what it's all for, but it's best to be left alone. |

I really think something should be done her now. There should be a forum vote about the implementation of this formula, or something. Honestly it is far superior to the one we have today, which is just awful, especially when it comes to albums with few votes. Again, because the numbers of votes on albums vary greatly, their score is not directly comparable. You can only try to make a formula that gives rather stable results, which is not biased towards any number of votes. The formula we have now does not produce stable results at all. As an example Fear of a Blank Planet has many times been pushed of the 2007 album of the year throne, by albums with much fewer votes, but it always reach the #1 spot again, as the album that passed it, gets more votes. This is just one example of the effects of how the rating formula is biased towards albums with few votes. And again, if the formula was good, it would be likely for the new #1 album at staying at the top, but it’s clearly not, because they always drop. Anyhow, the formula of Fight Club will be a great improvement in this respect.

^ I've been preparing this formula on my website ... unfortunately it's not ready yet, hopefully I'll have it online tomorrow. Now all you have to do is to rate albums on my website, so that we have a lot of data for the formula.

AWESOME! I have no idea how it will look on your site or how you made it applicable, but we'll see. And Sofagrisen, I am glad you approve so much of my new formula. We can only hope for the best  |

^ I'll simply add it to the chart page (http://ratingfreak.com/home/charts.xhtml), to the "Ranking Method" dropdown. The only problem is how to determine the fixed values of the formula automatically from the database.

Hey, how do I get the ratings to a 1-10 scale rather than 1-20? 10 makes a little more sense to me and I see you seem to have that scale in your signature.

^ I changed it for you. 0-10 will be the new common scale at Ratingfreak.com. But I think I'll implement a 5 star display in some situations (with partially filled stars of course).

Cool, I like the 1-10 scale. How's the formula coming along?

Ok, here it is: http://ratingfreak.com/home/charts.xhtml?chart.sort_mode=fc
A few comments: - In the calculation the averages used are combinations of arithmetic mean and median. - M is set to the average number of ratings per album of the query at hand (minimum: 5). - R is set to the average rating of all the albums of the query at hand. - The result of the calculation is currently only used for sorting the chart, the rating displayed is the standard average. |

I like it! But the current chart template isn't really suitable for comparing ranking algorithms, so I'll try to add some "display variations" later today. I'm thinking about a compact table which displays 50 albums at a time, with columns for the data used in the calculations. I'll let you know when it's available!
