Common probability distribution types and features

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

Probability Theory and mathematical statistics: random variables, distribution law, distribution function, Density Function

1: For N results in one experiment, if a real-value single-value function is matched for each result, the corresponding value is called a random variable. The mathematical definition is S = {e}. E is a sample in the sample space, and X = x (e) is

Introduction to Probability Density Estimation

1, Probability density function In classifier design (especially Bayesian classifier), when the prior probability of a class and the probability density of a class are both known, determine the discriminant function and decision plane according to

Khan Open Course-Statistical Study Notes: (3) random variables, probability density, two-item distribution, and expected values

Random Variable A random variable is different from a common data variable. It is usually expressed in uppercase letters, such as X, Y, and Z. It is not a parameter but a function, that is, a function. For example, the random variable X indicating

Patterns Recognition (Pattern recognition) Learning notes (vi)--nonparametric estimation of probability density function

In the last chapter, we studied the parameter estimation methods of PDF, which mainly have the maximum likelihood estimation and Bayesian estimation, they mainly estimate the parameters of the PDF with definite form, and in reality, we can't know

Probability and statistical knowledge Review (2) One-Dimensional Random Variables and Probability Distribution

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
