Different leads for away team analysis

As I did yesterday with home team leading, I did the same analysis for home team trailing or away team leading.
First we'll look at the one-goal differential, home team being down.






By taking a quick look, one sees that 1-2 gives the home team the highest chance of coming back. When the score is 2-3, the probability of coming back is smaller. As someone pointed out in a comment, this can be due to ability of adversary teams to score. It means that in a high scoring game, you have less chance to win, because either your defence is bad or your opponent's offence is strong.
Strangely, 0-1 is not the best score you can hope to see so your team maximisizes its winning chances. But the difference is relatively small with the 1-2 score.

Now ce can take a look at a two-goal deficit for home team.



As previously observed, 1-3 is better than 0-2 in terms of winning opportunity. My guess is that scoring a goal gives the home team a moral boost, whereas at 0-2 the players just wait for the game to end. Here the difference between the two scores is even greater than before until the 70th minute. Thois is the minute where many substitutions take place, so the "manager effect" equates the "moral boost effect"which is decreasing over time.

Allright, I think there are some things to learn from these short analysis :
 - Avoid high scoring game to maintain high chances of winning when team is leading.
 - When trailing, it is better to score at least one goal, to give moral boost and increase winning chance.
 - When leading, the winning chance increases over time. When trailing, the winning chance decreases.
 - The 70th minute seems to be critical when a team leads or is down 2 goals. At this point winning chances are converging to the same value no matter what the score is.

In terms of average Win% :
 - Reducing the gap from a 2-goals deficit to a 1-goal deficit increases Win% by 15.1%.
 - Tying the game increases Win% by 27.5%.
 - Taking the lead in a game  increases Win% by 32.6%
 - Increasing the lead to a 2-goals lead  increases Win% by 11.4%.

Goals created and Wins created

Like many others, I have the MCFC data set. I used it to toy with data and created two new statistics. In fact three, I'll explain later. The main thing I tried to do is to assess the impact of a player on the season in terms of scoring opportunities and wins. So first of all, I did some computation, and selected the data I needed:  - Appearances  - Assists  - Big Chances  - Goals  - Key Passes  - Time Played  - Shots I have to say that I'm not too happy with the data set. Many events are not recorded with a name, so you have data that cannot be used when you look at player production. But I managed to do what I wanted with the data. All data are from the MCFC data set, I rely on them for accuracy. First thing I looked at: topscorers. Rank Player full name Goals 1 Robin van Persie 30 2 Wayne Rooney 27 3 Sergio Agüero 23 ...
Win Probability Over Time It is often said that in football a two-goal lead will always yield a victory. But is that really true, and if yes to what extent? Well, this is the aim of my study, thanks to seven seasons of data. What we will basically do is analyze every possible situation, from trailing by 6 to leading by 6. Of course the timing will play a huge role. Because my data set is relatively small, I decided to regroup every result in 5 minutes brackets. Then this will give us the possibility to know the value of a goal in terms of winning chance. Of course in football there is the possibility of a draw so I will have two curves for each game situation. The first one with winning and draw percentage and the second with the simple formula: This will give us a good idea on a team chance of securing the three points. So with this second graph, a basic trend curve will allow us to calculate the Winning% at every point ...
