\over n-1}\right) \end{align*} $$ Note that it was approximately equal to 1 when $N $ was sufficient large (i.e. ${n-1\ove R N-1}\rightarrow 0$ when $N \rightarrow +\infty$). And then it's the same as the variance of the binomial distribution $\sigma^2 = NP (1-P) $, wherE $p = {M\over n}$. Examples1. At a lotto game, seven balls is drawn randomly from an urn containing notoginseng balls numbered from 0 to 36. Calculate the probability $P $ of havin

Domain parsing: var distribution problem, domain parsing var Distribution In JavaScript, you can declare multiple var statements at any position of the function, and they serve as if they were declared at the top of the function, this behavior is called hoisting (mounting/top resolution/pre-resolution ). When you use a variable and then re-declare it in the function, logical errors may occur. For JavaScript

How to generate a random number with a standard distribution or Gaussian distribution? Here is a method recommended by knuth pioneered by marsaglia: # Include

, Reverse greed (I call it reverse greed, do not know what to call) The process is probably like this (assigning m data to n person's head) 1.1 The data to be allocated m from large to small sort; 1.2 Remove n parts from the data m to assign the initial value to n individuals; 1.3 The data of this n individual from small to large sort; 1.4 Add n data from the data m to sum up the N person's head 1.5 Repeat 1.3-1.4 until data distribution ends B

EventDispatcher event distribution component and android event distribution mechanism Introduction Now you want to provide a plug-in system for your project. You can add some methods to the plug-in, or do something before or after some methods are executed without interfering with other plug-ins. To implement this system, a simple single inheritance method is not a good solution. Even if it is possible to i
