Random Variable A random variable is different from a common data variable. It is usually expressed in uppercase letters, such as X, Y, and Z. It is not a parameter but a function, that is, a function. For example, the random variable X indicating whether it is raining tomorrow is shown below. For example, if X = is a vehicle passing through an intersection every hour, a random variable is a description rather than a variable in the equation. There are two types of random variables: discrete an

First look at the great Gaussian distribution (Gaussian distribution) probability density function (probability density function): F (x) =12π−−√σexp (− (x−μ) 22σ2) f (x) =\frac1{\sqrt{2\pi}\sigma}\exp (-\frac{(X-\MU) ^2}{2\sigma^2}) Corresponds to the NumPy: Numpy.random.normal (loc=0.0, scale=1.0, Size=none) The meaning of the parameter is: Loc:float the mean value of this probability

What is a distribution view? The partial view of the MVC era, the corresponding ascx partial control of the Web Form era. Of course, MVC has more control over the distributed view.What are the advantages of the distribution view? 1, the distribution view can make the system plug-in (each function module is independent, reduce development, increase reuse).2.

The previous period of time the project has a demand, to click on the splash screen when doing some processing, just received this demand feel very simple ah, in the original view Add a button or gesture recognition what, the implementation of the back when the discovery or a bit of a pit. Whether I add a button on the splash screen or a gesture doesn't respond to the touch event, I've also thought of a number of possibilities, such as whether the message was delivered to another view, and I fin

In the design of a lottery program, it is sometimes necessary to have a probability that "there is a greater likelihood of getting a common result, a smaller possibility of getting a bad or excellent result", which can be obtained by using a normal distribution function.A series of randomly distributed functions have been provided in the STL, including normal distribution, Poisson

(Note: Only a little bit of information is forwarded for future reference.) Interested students please visit the original details. ）Dirichlet distributions can be seen as distributions above the distribution. How to understand this sentence, we can first give an example: suppose we have a dice, it has six sides, respectively, {1,2,3,4,5,6}. Now we have done 10,000 throws experiment, obtained the experiment result is six sides respectively appeared {20

For example, a random value rand (range: 1-100) is generated ). The probability of a small value in rand is very high, but the probability of a large value is very low. I hope you can give a specific formula. The random value can be replaced by rand. It is best to use code, such as PHPPython. thank you! For example, a random value rand (range: 1-100) is generated ). The probability of a small value in rand is very high, but the probability of a large value is very low. I hope you can give a spec

If 10 non-negative values are x1, x2 ,..., x10 meets the requirements of X1 + X2 + X3 +... + x10 = 1, are the 10 numbers evenly distributed between [0, 1? Apparently not. To illustrate this, the best way is to limit the distribution -- we can divide the [0, 1] range into several cells, it also shows that these 10 numbers cannot be evenly distributed in these intervals. For example, divide [0.25] into four sections: [0, 0.25), [0.5, 0.5), [0.75, 0.75),
