"Ah, it's finally done."

Chen Bo stretched his waist, this teaching evaluation is the most laborious he has ever done, more than a dozen 2000-word evaluations, it is better to go to the water essay.

"I'm almost there, one more." Wang Xu has been copying and pasting, and there are many people's evaluations that are almost the same, regardless of age, men are sunny and handsome, and women are gentle and kind.

"I don't know what the school is doing this, so many copies, does anyone read it?"

"I don't read it often, I look at it selectively, and the comments of outstanding teachers at the end of last year were excerpted from the evaluations we wrote." Wang Xu also pasted the last paragraph, and as the mouse keys of the submission fell, the whole person happily danced on the table.

"What? Is this a transcription of the conduction chain? Chen Bo looked at the time and exclaimed, "It's past 10 o'clock, and our dinner is in the soup." ”

"It's not a big problem, I can't go out to eat, just let them deliver it, I ordered takeout 15 minutes ago, and now the location shows that it is already on campus."

"You're really prescient." Chen Bo turned from surprise to joy, he didn't pay much attention to whether he could go out or not, as long as he could eat.

The drone slipped in through the cracked window with a thermal insulation box, and after scanning Wang Xu, it stopped in mid-air.

[Mr. Wang Xu, the order has been delivered, I wish you a happy meal]

"Alright, let's go."

"At first glance, I thought it was fried chicken." Smelling the fragrance, Chen Bo hurriedly moved his chair over to help.

"Pure bullfrog, self-deed, I'm moving."

Wang Xu ordered a large portion, the box was the size of the bottom of a mandarin duck pot, and the two sat opposite each other from near to far, and they were safe for the time being.

"I just looked at the resume of the teacher who taught Ma Zhe, and I didn't expect this guy to win the Benford Silver Award."

"What? A teacher who is engaged in ideological work has actually won a statistics-related award? Chen Bo, who was originally gobbling up, began to chew and swallow slowly, which showed that Wang Xu was burying his head in hard work, and suddenly felt that he had fallen into a trick.

"You also know that the Benford Award is statistically related, okay, I thought you would be confused." Wang Xu picked up the rice in his mouth while replying to Chen Bo's words.

"Can't we come back to this after we have eaten and drunk? I don't think you're a kid with a simple purpose. Chen Bo saw that half of Wang Xu's bullfrog had been picked out, and he was afraid that his side would be murdered soon.

"It's okay, I'm okay." Wang Xu put the ingredients on the sauce and took away a few bullfrogs in the range of Chen Bo's dinner plate by the way.

The taste of the takeaway point is really not bad, or it may be that the level of the canteen is really not good, Chen Bo wanted to fight again, but unfortunately there was no food, and it was not interesting to just eat food, so he didn't bother with Wang Xu.

"Aren't you eating? Don't tell me to lose weight. Wang Xu asked.

"No, I like to eat."

"You should order more." Wang Xu's proportion of meals is much higher than Chen Bo's, and he often doesn't move a few bites of food, and after eating so much, there is still a small half bowl left just to cover the bottom.

Chen Bo was full of food and drink, and he said without hesitation: "Let's continue to discuss what happened just now, how much do you know about Ben Fu's law." ”

"Not much, a rough understanding, if I remember correctly, the definition is that in the scenario of natural growth of numbers, in a group of numbers, the frequency of the first digit from 1 to 9 should gradually decrease, and the frequency of the first digit d should be roughly equivalent to log(1+1/d)."

"The probability that the first number is 1 is about 30%, and it gets smaller and smaller, the probability that the first number is 2 is 17.6%, and the probability that the first number is 9 is only a pitiful 4.6%."

"In layman's terms, when a set of average growth data starts, it grows more slowly, and the time it takes to grow from the initial number A to another number starting with A+1 will inevitably take more time than the number starting with A+1 to A+2, so the occurrence rate is higher."

"Yes, it's quite proficient." Chen Bo saw that Wang Xu was eating with relish, so he dipped some sauce with chopsticks and picked up all the remaining grains of rice in the bowl.

"This law can be applied to the field of accounting and finance, but it cannot be used as evidence alone, it can only confirm doubts and conjectures from the side, and provide a direction for people who have no clue to think."

Wang Xu cited the example of Enron's financial fraud, and some analysts used Ben Fu's law to find that the data in Enron's financial report did not conform to the distribution law, so they took further investigation and evidence collection.

In one of the U.S. elections, conspiracy theories were used to create a lot of conspiracy theories because one of the candidates had an unusually high rate of vote growth and the frequency of distribution of districts did not conform to Benford's law.

However, some mathematicians have pointed out that the ballot paper itself does not meet the scope of application of Benford's law, and in addition to the special circumstances of the year, the lag in the counting of mail-in ballots and the fact that the people who voted in this way are themselves more inclined to a certain political party, so it is reasonable that the law is untrue.

"This law is very magical, just like the C theory of the exam, I feel very disdainful just by looking at the definition, but when I encounter it, I will feel that it is really amazing, and I can't hide it." Wang Xu finished the last bite of the meal, and the tip of his tongue slid along his lips to clean the oil stains.

"Theory C, that's the official force of civil science."

Wang Xu corrected: "That is the crystallization of the wisdom of the masses, just like the Oxford Dictionary keeps pace with the times and includes Chinese English, nothing is immutable, and what adapts to the development of the times is a good thing." ”

Chen Bo nodded approvingly, the two cleaned up the residue, threw the empty box into the trash can outside the corridor, and bumped into a few girls who went upstairs, the other party looked at him with a little surprise, Chen Bo checked his appearance, except for the hairstyle was a little bohemian, there was no other indecent place, the clothes and pants were still alive, and the zippers were also intact.

"It may be the first time I've seen a boy live on the first floor, so it's good to get used to it." Chen Bo finished chatting and returned to the dormitory to prepare to wash and rest.

"It's about to be a holiday, and I can go home to be a salted fish again." Wang Xu was full of emotion.

"Isn't it too early?"

"I remember the last time you said you didn't want to read it, and the mayor advised you to come."

"I don't have that idea now, I love to read." Chen Bo pondered that the difficulty of this course was not to the point of destroying people's minds, and for the sake of money, it was not a big problem to stay up to complete his studies.

"It's good, after these few years, become a master."

"No, I just want to eat and die." Chen Bo didn't have any ideals in life, and when he was a code farmer, he was worried about commuting to and from work on time and getting enough sleep every day, and now it's not too much.

"Didn't your leader tell you to finish your studies and become a magistrate? You say you don't want to do it. ”

"And this good thing, as soon as it comes out, he will be a magistrate."

Chen Bo didn't expect this keyboard application major to be so good, as soon as he came out, he was a deputy ministerial-level cadre, and most of the Jinshi in ancient times were also county orders, and the probability of the title of the gold list was lower than that of keyboard application.

"It's okay to do it if you want to, go for it."

"Let's see."
