This article collects the miyi soccer network since the launch, you enthusiastic users to consult the more common, common, as well as more concerned about the issue. Here to carry out a collation and answer, convenient for everyone to view, in order to better use the site's Poisson distribution model soccer score prediction tool. If there is no mention of the problem, please Email Contact Consulting, we continue to update this article, in order to better serve you. Once again, thank you for your feedback and suggestions!

1, software prediction accuracy?
The results predicted by the model are all a matter of probability, and you can't just look at which predicted result has the highest probability and assume that which result will definitely occur. But anything that has a probability of occurring is likely to occur, the model's greatest reference value is to analyze the probability of occurrence of the results of each score.

2, why sometimes the data is empty or 0.01,99+ such results, there may be the following reasons:
（1）The current day's schedule has just been updated and involves a lot of data, which has not yet been fully updated and calculated. You can visit again in half an hour or so to see if the data has been updated.
（2）In the case that the start of the match is still a long time away from the current time, with a few days or so to go, the European oddsmakers have not yet opened the odds, and there will also be empty data. We need to wait for the next data update.

（3）If the match is a cup match, etc., there is no historical data of cup matches to calculate the Poisson probability. Because cup matches involve teams from a mix of high and low leagues, there is too much variation in strength to make a reasonable model calculation, so we also recommend that you avoid cup matches with too much uncertainty in your betting.

（4）The Poisson probability can't be calculated if there is no historical data on teams that have just been "promoted/relegated" in this league in an early season situation, so it will appear.

3、Can you view previous historical data?
Regular users can access the season schedule of "Free leagues", while advanced users can go to "All Leagues Pro" to view the historical prediction data of the matches according to the corresponding league schedule.

6. How to place a bet
POISSONFOOTBALL.COM only provides Poisson distribution model score calculation prediction tools, not betting services!

7. How to analyze data
①. The probability of an outcome calculated by the tool; the higher the probability value, the more likely it is that the outcome will occur; the lower the probability value, the less likely it is that the outcome will occur.

②. You can compare the results calculated by this tool with the probability of the European odds, if you are good at European odds analysis, you will be able to find the real direction of the game through the comparison of the difference between the two results, especially when the difference between the two results is large, there may be a cold game (Note: This method is a personal opinion, does not necessarily mean that the cold results will occur, please analyze the reference on your own, and only need to pay attention to the game). The match is only a hint of the matches that need attention).

8. Which is more accurate, the results of the 6-game analysis, 10-game analysis or the results of the 30-game analysis?

①. The results of our statistical analysis of the data show that the prediction approach for the 10 most recent matches turned out to be more accurate.

②. Predictions based on the last 6 or 10 matches are more reflective of a team's current form over a period of time.

③. The results of 30 recent games are predicted to give a more objective reflection of the true strength of the team.
④The three results should be combined to find more information to compare and analyze; for example, you can look up the team's recent game trends, the team's intentions, and other information.

9、Data description of calculation results (meaning of key data):

①.  Home/Away xG: the theoretical number of goals scored by each of the home/away team calculated according to the Poisson distribution formula model.

②.  Home team win probability / draw probability / away team win probability: Poisson distribution formula model calculated according to the game win, draw, negative results of the respective probability of percentage, the results for the "score probability distribution" table below the specific sum of the probability of each win, draw, negative score.

For example： Draw% = （0:0）+（1:1）+（2:2）+（3:3）+（4:4）+（5:5）+（6:6）+（7:7）Sum of probabilities (blue probability values on the slash of the table)

③. Probability distribution of goals: the probability of the home/away team scoring a few goals in the game, calculated according to the Poisson distribution formula model.

④. Score Probability Distribution: The probability of a specific score occurring in the game, calculated according to the Poisson distribution model.

10, Does the value of the Poisson probability change for each game?

The Poisson probability, which is calculated based on the games this team has finished prior to this game, does not change once it is calculated.

本篇文章收集了POISSONFOOTBALL.COM自上线以来，各位热心的用户咨询的比较多的，常见的，以及大家比较关心的问题。在此进行一个整理与回答，方便大家查看，以便更好的使用本站的泊松分布模型足球比分预测工具。如有未提到的问题，请Email联系咨询，我们后续持续更新本文，以便更好的为大家服务。再次感谢各位的反馈及建议！！！

1、软件预测准确率高吗？
模型预测的结果都是一个概率问题，不能单看哪个预测结果的概率最大，就认为哪个结果一定会出现。但凡有概率出现的事情，都有可能会出现的，模型的最大参考价值是分析各个比分结果出现的概率。

2、为什么有时数据是空的或者0.01这样的结果，可能有以下原因：
（1）“Today”赛程刚刚更新，涉及到的数据比较多，还没有完全更新、计算完成。可以隔上半个小时左右再访问，看看是否数据更新完成
（2）比赛开始时间距当前时间还比较长，有几天左右的情况下，欧赔公司还未开出赔率，也会出现空数据情况。需等待后续数据更新

（3）如果比赛为杯赛等情况下，没有杯赛的历史数据，无法计算泊松概率。因为杯赛参赛球队为各高中低联赛混赛，实力差异太大，无法进行合理的模型计算，所以我们也建议您购彩时避开不确定性太大的杯赛比赛。

（4）如果在赛季初期情况下，没有此联赛刚刚 “升/降级” 球队的历史数据，无法计算泊松概率，所以会出现。

3、可以查看之前的历史数据吗
普通用户可以访问 "免费联赛 "的赛季赛程，高级用户则可以进入 "所有联赛专业版"，根据相应的联赛赛程查看历史比赛预测数据。

4、如何注册
点击顶部的 "Sign Up"链接进入注册页面，填写信息注册成为本网站用户。验证您的电子邮件地址后，新用户将获得为期 3 天的 VIP 高级功能试用期（仅此一次）。

5、如何预测
请在PC端或者小程序端访问“ "How to use" ”

6、怎么下注
POISSONFOOTBALL.COM 仅提供泊松分布模型得分计算预测工具，不提供投注服务！

7、如何分析数据
①、工具计算出来的某一结果的概率，概率值越大，越可能会出现此结果；概率值越小，出现此结果的可能性就越低。
②、您可以将本工具计算出的结果与欧赔的概率进行对比，如果您擅长欧赔分析，就能通过对比两个结果的差异找到比赛的真正走向，特别是当两个结果差异较大时，可能会出现冷门（注：本方法仅为个人观点，并不代表一定会出现冷门，请自行分析参考，只需关注比赛即可。）本场比赛只是提示需要关注的比赛）。

8、6场比赛分析、10场比赛分析和30场比赛分析的结果哪个更准确？
①.我们对数据的统计分析结果表明，对最近 10 场比赛的预测方法更为准确。
②.基于最近 6 场或 10 场比赛的预测更能反映一支球队在一段时间内的当前状态。

③.预测最近 30 场比赛的结果，更能客观地反映球队的真实实力。 

④要把三种结果结合起来，找到更多的信息进行对比分析，比如可以查询球队最近的比赛走势、球队的战意等信息。

9、计算结果数据的含义
①、主队/客队预期进球数： 根据泊松分布公式模型计算出的主客队各自理论上的进球数

②、主队获胜概率/平局概率/客队获胜概率:  根据泊松分布公式模型计算出的此场比赛出现胜、平、负结果各自的概率百分比，此结果为下方“比分概率分布”表的具体各个胜、平、负比分概率的总和。

例如： 平局概率 = （0:0）+（1:1）+（2:2）+（3:3）+（4:4）+（5:5）+（6:6）+（7:7）概率(表格斜线上蓝色概率数值)总和

③、进球数概率分布： 根据泊松分布公式模型计算出的主客队各自在本场比赛中进几个球的概率

④、比分概率分布： 根据泊松分布公式模型计算出的本场比赛出现的具体比分的概率

10、每场比赛的泊松概率数值会变吗？

泊松概率，是根据此队本场比赛之前完赛的比赛进行计算的，一旦计算出来了，是不会改变的。
