Statistics Fundamentals: Descriptive Statistics
Statistical analysis is divided into two fields: descriptive statistics and inferential statistics. Descriptive Statistics is the technology for describing or characterizing existing data and is the …
Inferential Statistics: The Past and Present of p-values
The core of inferential statistics lies in hypothesis testing. The basic logic is based on an important argument from philosophy of science: universal propositions can only be falsified, not proven. …
Basic Concepts of Probability Theory
Basic knowledge notes on probability theory: axiomatic foundations, probability calculus, counting, conditional probability, random variables and distribution functions
Fundamentals of Information Theory: Entropy
Reading notes on 'Elements of Information Theory': What is entropy? Entropy is a measure of the uncertainty of random variables, and also a measure of the information needed to describe random …
Humans, Society, and Neural Networks
Neural networks emerged inspired by the human brain, so the operational mechanisms of human society also have various similarities and connections with neural network training. Some thoughts on …

Basic Concepts of Probability Theory
1. Set Theory Sample space and sample points are undefined basic concepts in probability theory, like the concepts of points and lines in geometry. Definition: Event Event: An event is a set of sample points. $A=0$ means event A contains no sample …
