Test of normality distribution 1. The Observation Act X is the data you want to examine. hist (x); % frequency histogram (see whether the naked eye is symmetrical, middle more, less on both sides) 2. Observe the method Histfit (x);% normal curve fitting normplot (x);% normality test (whether discrete points are distributed on a straight line, indicating that the samples are from normal distribution, otherw

3.1 Two-Point Distribution and even distribution1. Two-Point DistributionMany random events have only two results. If the result of the product is qualified or unqualified, the product or reliable work may fail. This type of random event variable has only two values. Generally, 0 and 1 are used. It follows two-point distribution.Its probability distribution is:Where Pk = P (X = Xk) indicates the probability

Based on the guarantee of data quality, the distribution and contribution of data are analyzed by drawing charts and calculating some statistics (Pareto analysis), distribution analysis can reveal the distribution characteristics and distribution types of data, and for quantitative data, we can make frequency

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 complex. The distribution frame of a building is a connection device con

Sixth chapter sample and sampling distribution Content Summary First, the overall In mathematical statistics, the whole of the research object is called the whole, and each element that makes up the whole is called an individual. The overall use of a random variable x represents. If the distribution function of X is f (x), the F (x) is called the distribution fun

I have previously written a research plan on the mechanism of Population Spatial Distribution in China and its simulation. The question is very big, and I don't think deeply. It is a rough idea. China is experiencing the largest population movement and migration in human history. According to the latest data from the sixth census, China's current urbanization rate is approaching 50%, in the future, China will enter a period of rapid urbanization, and

7.2 Two-Item distribution algorithmAuthor Bai NingsuAugust 15, 2015 22:51:38 Abstract: In this paper, the study of the geometric distribution of statistics, two distribution, Poisson distribution in depth, based on a variety of distribution of basic concepts and cor

Building a Linux distribution of its own is a dream for every free open-source software enthusiast. It was once a very difficult thing to do, a Linux distribution is also rare, can do a Linux distribution has been extremely glorious things. But, by itself, to promote its own potential, To promote their own practical spirit of the free open source world, is not to

Theshortletdistribution Dirichlet distribution (PRML2.2.1) Dirichlet distribution can be seen as distribution above the distribution. To understand this sentence, let's take an example: Suppose we have a dice with six sides: {1, 2, 3, 4, 5, 6 }. Now we have performed 10000 throwing experiments. The results are displaye
