PDF versionPDF CDFThe probability density function is $ $f (x; \mu, \sigma) = {1\over\sqrt{2\pi}\sigma}e^{-{1\over2}{(X-\MU) ^2\over\sigma^2 }}$$ the cumulative distribution function is a defined by $ $F (x; \mu, \sigma) = \phi\left ({x-\mu\over\sigma}\right) $$ where $$\phi (z) = {1\over\sqrt{2\pi}} \int_{-\infty}^{z}e^{-{1\over2}x^2}\ dx$$Proof:$$ \begin{align*} \int_{-\infty}^{\infty}f (x; \mu, \sigma) = \int_{-\infty}^{\infty}{1\over\sqrt{2\pi}\s

The practice, like everyone else, has been understood,ran = Random.random (), is a random floating-point number that produces between 0 ——— 1,such as the next code, the first randomly generated number less than 0.1 probability is 10%, if the first number is greater than 0.1 is the probability of the first take and after the problemImportRandomdefSelect (): Num_= ['a','b','C'] #

Chapter One basic concepts of probability theory Content Summary: A. Principle and arrangement of addition and multiplication, and review of Combination 1. The addition principle is set to complete one thing there is a class method (either of these methods can be achieved The purpose of accomplishing this), if the 1th kind of method, the 2nd class method has the kind, the first kind of method has the kind, then completes this matter to have a total of

Use -- random number usage and probability of generation, random number Probability The Random class is used to generate Random numbers within a specified range. The constructor has two types of constructor without parameters and parameters. The constructor with parameters has the number of seeds. Assume that the following r is a Random object Random r = new Random (); 1. generate any integer Int

n-m b event appears M The probability of the occurrence of the time (corresponding to a composite event) P should be ( here p is uppercase ) P =[n!/m! ( N-m)!] [pn-m(1-p)m] Notice the symmetry of the above formula, which can also be written as P =[n!/m! ( N-m)!] [pm(1-p)n-m] It is the probability formula for the occurrence of ra

To ensure the normal operation of the equipment, a certain number of equipment maintenance personnel are required. There are 300 similar equipment and each equipment works independently. The failure probability at any time is 0.01, if one person repairs a device fault, how many repair personnel should be assigned at least to ensure that the probability of timely repair after the device failure is not less t

chapter focuses on the concept and distribution of statistics. Analysis of typical examples Example 1. Set X1,X2, ... Xn is a sample from the overall x, in the following three cases, the E (), D (), E (S2) are respectively obtained. (1) x~b (1,p), (2) x~exp (λ), (3) x~u (0,θ); Analysis: It can be solved by using the expectation of common distributions, variance, and the property of S2 definition and expectation variance. Solution: (1) due to x~b (1,p), E (x) =p, D (x) =p (1-p). So E () =ex=p, D

This kind of thinking often makes my life very painful. When you want to finish something quickly, your mind is no longer in this matter. This problem has plagued me for a long time in college. I don't realize that this is actuall
