Original ball warmers article: http://arstechnica.com/gaming/2014/04/introducing-steam-gauge-ars-reveals-steams-most-popular-games/
Registered on Steam account (Steam users who purchase) approximately 37% of the game, is being neglected by the number 781 million games have not played ball warmers before. I poured Steam users will pour 3.8 billion hours are summed to play Dota 2. Another Steam users are almost six times more than the time which are in the single-player game kolop: Modern Warfare ball warmers 2 was used for the multiplayer.
Movies, ball warmers Music (Music), in the area of TV broadcasting attendance, album sales, and there are relatively credible medium to aggregate the ratings. ball warmers However, the video game area manufacturer or distributors - when the achieved monumental breakthrough performance as a million copies - a situation that must rely on the figures released occasionally. While the largest number of public dongjeopja 100 different games that run on the most popular platforms in their own steam, and this figure does not show the entire fluid volume and total play time and games specifically. ball warmers
We came up with a way for the general users, too (in steam) published a more accurate information on the basis of the game can be calculated that can access the volume and a play time. We could all games of sales and steam users registered on the basis of the steam in the past few months are able to produce such a way how long to play each game. How we used to collect data is as follows:
All you need to track your game on Steam sales information was hidden near than you think. Key information gained steam in the individual user's personal profile page which can be accessed via the Steam Community of the valve. We were here, each user can see the full list of games you have on your own steam amendment. Also in the rainforest users to determine how long you might have to play the game holds its own. Which is actually more important than what's to access the individual user profile pages, in fact, there was no need to manually verify the individual's identity (ID). The address of your profile page is made in the form of (http://steamcommunity.com/id/ user ID). But steam in a secret code number of 17 digits in each of the separate identity ball warmers and grant management. ball warmers So if you know your own code (http://steamcommunity.com/id/17 digit secret code) scheme can be accessed ball warmers on their profile pages, such as steam.
Steam currently has approximately 100 million personal profile page 7000 amounted to 2 million pages. In theory, if we examine every page manually create a total list of games Steam users are held and will be able to be sorted from the most sold game in order. But the equipment that we have is was not possible to survey and classify web pages over the period ball warmers of just a massive 100 million pages.
We would ragon with random sampling (how to select a valid object of a number of candidates) understanding of the technology and scrap more than 100,000 pages per day (detect and classify the information collected) the case of Amazon EC2 server capable of we itgetda be used in the survey was about. Based on our understanding (as described above) for the Steam Community ID system (and added a bit of knowledge of PHP / MySQL) we went accumulating data provide different ball warmers personal profile page at random by about two months on a regular ball warmers basis. In this way we were able to extract the common data for Steam game sales and gameplay time.
Once back, except for private and invalid profile page, we made (extract) geonnae 9 day program gave a list of valid personal profile page worth more to us from 80,000 million. We (and for how long you have to play) to buy and play a particular game from the list, and made a calculated ratio (%) of the steam users. ball warmers And we have multiplied the value according to the ratio of the total number of registered personal profile page numbers and steam extracted sample page.
We can have 90,000 pages doubt whether you can ensure the reliability ball warmers of the expected rate of 0.04% at best result in a very large share of the total first glance looks at more than 100 million pages of 80,000 was used as a sample. However, random sampling is a statistical technique that statistical errors are trusted by only require a 0.33%. Parliament, despite approval ball warmers ratings candidate in the presidential election survey results from only a few thousand respondents is quite accurate in things like reason.
However, to ensure the more carefully the accuracy we are pulled further into the sample every three days was added to the daily irradiation reflect the result on the final estimate. Which we dispose of daily data and further 3 days (the time of the three-day reflection) Updated (New anyways) it means that the alternative to the sample (profile). In this way we were able to extract ball warmers data from almost any time, effective steam personal profile samples over the whole study period, more than 25 million.
Of course, if you wrote your own private user profile during the steam is also extracted a sample we can not have so many things perfect. While private users are also able to exclude the possibility jinyeoteul the purchase method, the gameplay and the general attitude of the different user types, we have determined that private users are very insufficient impact on the overall statistics. In any case you wrote your own user profile, private profile did not exceed 6% of the sample we extracted.
Our statistics while maintaining confidence in the calculation method, if we can check the accuracy and reliability without comparison ball warmers (number and playing time in the game on sale on Steam) information and our statistics published by other routes of us and disclose statistics ball warmers on public may not have the slightest doubt shake abandon. Fortunately, we already have our data and resources in both the public sources and be treated in a confidential internal industry in general could compare a few times. And was pleased to discover that they could be significant common denominator.
For example, March 28 producers of DayZ Dean Hall has said sales of DayZ standalone ball warmers version through Steam Early Access and reached 1.7 million copies. Our measurements at that point was still pointing to 1.76 million copies. In a similar case, Rust's producer Garry Newman said neomgyeotdago you have the Steam sales of one million copies in Rust Feb 10 via Twitter. Our measurements show had sales of Rust and reached 93 million ball warmers copies at that time. Some difference of 70,000 copies, but the difference is (became more sampling operation for the next two days) in just two days was mekkwo. Through these results we have for the game to reflect the reality of our research method, this volume shows up in full speed occurs a slight time lag. This can be described ball warmers as our samples flowerbed logical consequence to occur because the iteration and updating the accumulation of 3-day intervals.
Some of the steam creators of our sales resources to help their investigation (on condition that no external public) were willing to share. With their help we could expect not only more accurate results, we could have a little more confidence in the results came up calculation. But at this point to emphasize once again seems to go beyond. Our findings ball warmers will came up with a sample drawn from a limited number of small steam personal profile. So the objective facts, but may not be able to accurately show the difference (the difference between the actual value of our findings), we thought it would be limited to at most a few percent confident. In addition, as previously described research in the case of a very low level of the game is likely to be included in the sample do not sell games or contrary sold almost done came out at a faster rate at the time of the proceeding, the possibility that our findings are a bit more high not properly reflect reality We look can. If you are (registered on Steam), ball warmers creators of the game and want to share with you (sales) data, please contact us at any time. Will help to provide further erado modified data.
One more thing is the fact that not Pinch want to go beyond the data we deal had steam glad to show the approximate outline of the entire ball warmers PC game market is still showing that the whole truth. Steam gamers as well as the Battle.net, oil play, origin, GOG, geyimeojeu gate, and play games using digital platforms, etc. for Sura, purchasing the package, there are also users who play through the disc. Of course, these numbers are not reflected in our survey results. ball warmers In view of the foregoing say that the action ball warmers is well-known digital platform exclusive games, our findings are also present as a whole lot other than Steam PC game market has insufficient surface.
In some cases, you might not think of a game to be released as a multi-platform. For example, for the Sims 3 through the steam, according to our investigation
