This is a parabola-like curve, with the X-axis representing the odds of winning a single game and the Y-axis representing the odds of a particular tiebreaker.

Chen Bo used a tool to take a few evenly distributed points, and the results showed that when 0.5

According to similar ideas, Chen Bo deduced the model of 4 wins in 7 games and 5 wins in 9 rounds, the curves are similar, and the answers are self-evident.

For the higher the level, the more rounds are used, the greater the chance of winning, which is in line with Chen Bo's inherent cognition.

A game is the most likely to cause an upset, and a strong team will be overturned by a strange move if they are not careful, and as the number of sets increases, the impact of this potential risk will be greatly reduced.

Chen Bo moved his wrist, he had been abused for so long, and finally tested some professional knowledge.

Wang Xu on the side was still looking at the computer in a daze, and Chen Bo leaned closer, trying to point out one or two to save his personal image.

"What are you?"

The model on Wang Xu's screen is three-dimensional, and it looks much more complicated than his own, and Chen Bo didn't dare to say anything.

"The impact of buying different products on the level of well-being." Wang Xu read a long list of questions slowly.

"Where's the homework assigned by the teacher?"

Wang Xu said indifferently: "I don't need to draw if I think about it, and the common sense of life tells us that when you have more chips, the more you must play steadily." ”

"Looking at your villainous sly smile, you must think you've solved a great problem, are you interested in trying this problem?"

Wang Xu zoomed in on the model, it was still a parabola just now, and the roller suddenly became a straight line that fluctuated up and down after a few turns.

"The change of mood is affected by many factors, in addition to the type of goods highlighted in the title, the motivation for purchasing, the time node, one's own property status, and even the weather will become factors that cannot be ignored."

"This may be a bit abstract to say, but I'll explain it with a numerical value, let's say you buy a bracelet and the pleasure increases by 20 points; If you buy a sweatshirt, your pleasure will be increased by 10 points; Just pay salary, empty shopping cart, pleasure increased by 30 points; At the end of the month, he was poor, borrowed and consumed, and his pleasure did not increase or decrease. ”

"When we look at the above factors separately, it is easy for us to distinguish them, but when they are mixed together, how to judge the proportion of each is what I want to know at the moment."

"The question asks how much a shopaholic's pleasure changes when she consumes a 200 yuan lipstick at the end of the month, and whether this change exceeds the historical average, please use data to prove it."

"The calculation of the value of pleasure is the key, but I only have a few charts in my hand, and according to different calculation methods, I can come up with at least 8 answers, and the error between them is obviously beyond the allowable range, how to choose?"

"Hey, I've said so much, are you listening?"

"Very good, Immortal Wang." Chen Bo applauded in agreement, "Contemptible people are not talented, such a profound academic issue, you can study it slowly." ”

After feeling his insignificance and humility, Chen Bo took the initiative to choose to move closer to a higher level.

The dynamic model was born from the traditional static model, which can better adapt to the needs of the development of the times, and when experts and scholars in the past studied a certain phenomenon, they would always list the data as a scatter plot and spread it on the coordinate axis, and calculate a regression curve from this.

Although this can intuitively summarize the law of development in a certain period of time, it ignores the volatility in the process of the progress of things, and some details are simply skipped in a few words, and do not get due attention.

Mr. Xu Bowei was deeply affected by this, using a static model to explain the unpredictable stock market, and making trading actions based on it, which is difficult to think of without losing money.

Xu Bowei did not want to live or die like a glass-hearted retail investor, and he put forward a set of improvement plans, which is now regarded as a dynamic model by the industry.

Relying on historical data, combined with real-time adjustment and rigorous logical analysis, Xu Bowei discovered the mystery hidden behind it, and immediately returned to the stock market with the attitude of a king.

In the end, he succeeded in a debt of one million.

Mr. Xu Bowei once again showed the courage of a cow, he wrote all his mental journey into the journal works, and did not shy away from placing it in the classroom as a negative teaching material for the students.

If you fall in one place, don't be afraid, get up and keep running; Fall into the bottomless abyss, don't panic, tell others that you have been here.

This is the motto printed on the book cover, but it is more like an epitaph, full of pathos.

Other science bulls are indifferent to fame and fortune and devote themselves to contributing to society, Xu Bowei belongs to Lao Tzu who wants to make a fortune, but he has no choice but to go bankrupt and can only make a living by writing papers.

It can't be said which is better or worse, it's just that Xu Bowei's road legend has a stronger charm.

The opposite case is that at first glance it is a K-line chart, but the parameters are much more complex, not only involving the overall layout of the stock market itself, but also taking into account the external environment.

At the macro level, the main focus is on major events, such as the promulgation of major policies, the sudden change in the international situation, and the strategic adjustment of giant enterprises.

From a microscopic perspective, the explanation of an anomaly at a certain point in time can be described as everything, accurate to a few minutes.

It can be said that this is almost a half-open game, and it can lose so completely, which reminds Chen Bo of a certain landlord philanthropist on Shark TV.

In the chart, every step of Xu Bowei's operation is reviewed, at first, through accurate chasing up and down, his profit and fluctuation once reached 30%, but Xu Xueba is not satisfied with a small fight, he wants to play a big ticket.

10 times leverage is a good thing, Xu Xueba calculated the next peak period, and joined the mountaineering team without hesitation, but the dealer started the combine harvester in advance and crushed Xu Bowei to death halfway up the mountain.

For the first time in my life, I knew that I could borrow that much money.

This is the reflection summed up by Xu Bowei, who has a clear brain, after losing all his money, he regained his strength and waited for the opportunity to fight again.

If the odds of winning or losing are reasonable, there is a rule of making sure that you don't lose money, called the doubling betting method, assuming that the odds are 2, then the multiplier of each round is 2, there will always be a time to win.

There are two prerequisites for this to be achieved, one is that the stake is unlimited, which allows you to take out enough money to continue betting after a losing streak; The second is that the probability is constant, after all, some things are one set on the surface and another set behind the scenes.

Dealer: Don't worry, my knife is fast.

"This annotation is so real." Chen Bo laughed unkindly.

Xu Bowei's leek career stopped here, in fact, if he held on for a few more days and survived until he rebounded, at least half of his money would be recovered.

Xu Bowei's loss of money was recovered through the copyright fees of his book, and "The Self-cultivation of Retail Investors", which was written by others and named by himself, has won the annual sales champion of economics and management books for 3 consecutive years.

"Sure enough, the big guy will shine wherever he is."
