[認真]美斯同C朗 邊個射門勁啲？

應該佢地以後都唔會再講數據

贏入波果期就鬥助攻
贏助攻果期就鬥獎盃
國際賽獎盃都贏埋就開始轉風鬥咩轉化率、key pass
龍門任你擺

美斯完爆C朗
完。

以為王大哥開po

拿卡勁到排第二

係呢度就屌數據無用，另一邊就屌摩笛入波助攻少，人唔笑狗都吠

睇你點睇架咋
好似做sales咁，有啲見個客有心買先落力sell, 咁就命中率高啲
有啲對所有客都落力sell, 命中率自然低
最後結果可能一樣，大家都係開咁多張單
但當你每個機會都唔放過，客觀以言，成功開單嘅機會點都係大啲。
你係老細想要邊個多啲？
如果你每季抽起牙朗500腳射門，可能佢入球數只係少5-10球，命中率即時靚仔晒
因為呢個數劇係分析唔到每個射門嘅入球機會大細，果500腳射門命中機會可能只得1-2%, 但牙朗係連呢1-2%都唔放過。

你post數據個陣
佢地都轉移話題屈你朗迷咋嘛
幾時有討論過數據

你都可以咁講
但你睇返賓斯馬喺呢份數據分析個排名，對比返今季佢喺皇馬表現
交波比佢入球機會都未必高過自己射
BTW, 我只係想指出呢份數據分析個盲點喺邊

啱呀，所以如果話牙朗浪射，我係同意
但如果拎住呢份數據分析話牙朗把握力差，我會覺得係ON9

1 – Firstly, not all shots are the same, i.e. they have different probabilities to be transformed into goals. Some shots are easy to be scored and some are more difficult. Also, different players tend to take different type of shots and because of this, directly comparing their conversion rates wouldn’t be a fair way to judge on their finishing ability.

One reasonable way to deal with this is to build/apply an expected goals model to our data and then to categorize shots based on the expected goal value, allowing us to take into account the difficulty of each shot. Unfortunately, we don’t know enough parameters to do this. Instead, to categorize shots, we will use the only parameter we have: the distance from the center of the goal. This is obviously not ideal, since the shot difficulty depends on many other variables, but considering that the distance from the goal is the most influential parameter in almost every expected goals model, it makes sense to use it. This will hopefully allow us to take into account shot difficulty.
呢兩段佢自己都承認好難客觀比較每一個射門難度，所以佢個expected score係用"the distance from the center of the goal", 呢個就可以客觀d.
係o既，都係牙朗差d，但就係因為我地無法扣除浪射o既數據嘛

你有睇開的話，應該都多過我

我本身唔多就咁上嗰啲數據網睇。講真，唔真係有研究開，其實望住堆數據係冇乜意思。要將啲數據砌得有意義、visualize到俾人睇嘅，先係真正難處。好似呢篇野咁，唔係啲圖，根本冇人會知啲conversion rate差嗰小小有幾大分別。

我自己就睇開Twitter，嗰啲pro嘅人會寫文做數據分析，學吓野咁。依幾個都出名，又好睇：

單純數據的話，免費又多野睇的就 WhoScored.com，但我唔係好中意

上面都有人提過嘅Understat，就係少有免費嘅xG網站。

冇人話要減呀，就係話唔可以減呀
就係正如你所講無法客觀定義邊啲係浪射，邊啲係機會
數劇分析就係每一腳都要計
你睇清楚人講嘢先啦，咪on9 ok?
