ecwid square

Defined:If our random variable is a standard normal distribution (see the Gaussian distribution of previous blogs), then the squared and subordinate distributions of multiple random variables are chi-squared distributions.X=y12+y22+?+yn2Among them, Y1,y2,?, yn are to obey the standard normal distribution of random variables, then xx obey Chi-square distribution, it is worth noting that the NN is the number of random variables become chi-

The chi-square test is the deviation between the actual observed value and the theoretical inference value of the statistical sample. The deviation between the actual observation value and the theoretical inference value determines the size of the card square value, the larger the card square value is, the more it does not conform; the smaller the value of the ca

How to rewrite the Russian square in C and the Russian square in CI used to write a Tetris in C language, but I haven't read the program since I wrote it. The source code is too bad for anyone to read. I also posted the source code on the Internet. I really don't know what I think. Maybe it was the first time I wrote a program that I always wanted to write. So I'm very excited. I believe that many people wh

If P = 2 or P = 4 * k + 1, P can be expressed in the form of the sum of two degrees (Euler and ferma have proved and have an exact method). Therefore, the answer is P. If P = 4 * k + 3, set a ^ 2 = N (mod p) (n! = 0) it can be proved that there is no B, B ^ 2 = p-n (mod p). That is, if n is the square residue of p, p-n is not the square residue of P. Proof: because a ^ 2 = N (mod P), N ^ (p-1)/2) = 1 (mod

Chi-square test is a hypothesis test method for counting data with a wide application. It belongs to the category of Nonparametric test, which mainly compares the correlation analysis of two and over two sample rate (composition ratio) and two categorical variables. The fundamental idea is to compare the theoretical frequency with the actual frequency of the degree of coincidence or goodness of fit problem. (More reference: chi-
