Bayesian Theorem explains common knowledge

A distribution frame is a device for end-to-end and connection of cables or optical cables. Interconnect or hand over the distribution frame. The complex distribution frame is a connection device connecting the trunk cable and optical cable of the

Probability theory is a branch of mathematics that studies the law of random phenomena. Its origins in the 17th century century, at that time in the category of error, demographic, life insurance, need to collate and study a large number of random

1 Statistic Quantity
Statistics: Constructs a function from a sample, without relying on any parametersCommon statistics: Sample mean (X¯), sample variance (S 2), sample variation coefficient (V=sx¯), sample K-Order distance, sample K-Order center

1. Concept of Random Variables
As the name implies, a random variable is a variable with a random value. The opposite of a random variable is a "deterministic variable", that is, the variable whose value follows a certain strict rule, such as the

Origin of 1,t test and F-Test
In general, in order to determine the probability of making a mistake from the statistical results of samples (sample), we use statistical methods developed by statisticians to perform statistical verification.
By

1. Origins of t-test and F-test
In general, to determine the probability of making mistakes from the statistical result of the sample to the overall result, we will use some statistical methods developed by the statistician for statistical

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
