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%.

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 ...

Win Probability Over Time (Final)

After crunching the number and the data, I came up with nice equations for each score. This allow me to create a table showing the Win probability at every minte for a score differential of -3 to 3. But the two extreme cases are not as accurate as the others. One can check the R² later in the post. So here is the final graph. Trailing by 1 Trailing by 2 Trailing by 3 Tie Leading by 1 Leading by 2 Leading by 3 R² = 0,7074 R² = 0,71 R² = 0,1234 R² = 0,2581 R² = 0,9007 R² = 0,8253 R² = 0,2019 So from these I derived the marginal winning chance provided by a goal. I only used the goal differential -2 to 2 because I want to keep the most accurate models. On the graph, T means trailing and l means Leading. So for example the graph T2-->T1 means the winnig probability added by going from a 2 goal deficit to a 1 goal deficit. If m...

One-goal and two-goals lead analysis

Continuing on my football resultss analysis, I want to analyze 1-goal and 2-goals lead. The main question is : does every score yields the same winning chance? Of course we keep scores with the same differential, for example home team is one goal up. So I ploted on the same graph the Win% for 1-0, 2-1 and 3-2. First thing you will see in the graph below is that 2-1 data starts at the 15th minute and the 3-2 data starts at the 45th minute. All data points are regrouped in 5-minutes window to correct for the sample size. What you see is that basically, Win% increases over time. But something more interesting is the trend. It seems that when the score is 2-1, the home team has less of winning (or to draw, as I count a draw as half a win). The difference is slighlty over 5%. When the score is 3-2, the curve is also below the 1-0 curve for most points. When building nice fitting curve for 1-0 and 2-1, the trebd is clearer. Even if the effect is not huge, it is interesting to no...
