Introduction to data analysis methods
Common data analysis methods: 1. Comparative analysis method; 2. Structural analysis method; 3. Cross analysis method; 4. Trend analysis method; 5. Cause and effect analysis method; 6. Correlation analysis method; 7. Cluster analysis method; 8. Principal component analysis method; 9. Scatter analysis method; 10. Matrix analysis method. Detailed introduction: 1. Comparative analysis method: Comparative analysis of two or more data to find the differences and patterns; 2. Structural analysis method: A method of comparative analysis between each part of the whole and the whole. ; 3. Cross analysis method, etc.
There are many methods of data analysis. The following are some common methods:
Comparative analysis method: Comparatively analyze two or more data to find the differences and patterns.
Structural analysis method: A method of comparative analysis between each part of the whole and the whole.
Crossover analysis method: At the same time, two variables and their values that have a certain relationship are cross-arranged in a table, so that each variable value becomes the intersection point of different variables. Generally, two variables are used. Dimensional crosstab for analysis.
Trend analysis method: Analyze the development trend of data and use it to predict future trends.
Causal analysis method: Analyze the causal relationship between data to explain why things happen.
Correlation analysis method: By analyzing the correlation between data, find out the association rules and degree of correlation between the data.
Cluster analysis method: cluster data according to certain characteristics and rules, and classify similar data into one category.
Principal component analysis method: Through dimensionality reduction technology, multiple variables are transformed into a few comprehensive variables to reflect the main characteristics of the original data.
Scatter analysis method: express the relationship between two variables through a scatter diagram to observe the correlation between variables.
Matrix analysis method: Analyze data in the form of a matrix, which can be used for correlation analysis, cluster analysis, principal component analysis, etc.
The above are some common data analysis methods. Each method has its own characteristics and scope of application. Choosing the appropriate method for data analysis can help better solve problems and understand the data.

11 basic distributions that data scientists use 95% of the time
Dec 15, 2023 am 08:21 AM
Following the last inventory of "11 Basic Charts Data Scientists Use 95% of the Time", today we will bring you 11 basic distributions that data scientists use 95% of the time. Mastering these distributions helps us understand the nature of the data more deeply and make more accurate inferences and predictions during data analysis and decision-making. 1. Normal Distribution Normal Distribution, also known as Gaussian Distribution, is a continuous probability distribution. It has a symmetrical bell-shaped curve with the mean (μ) as the center and the standard deviation (σ) as the width. The normal distribution has important application value in many fields such as statistics, probability theory, and engineering.
11 Advanced Visualizations for Data Analysis and Machine Learning
Oct 25, 2023 am 08:13 AM
Visualization is a powerful tool for communicating complex data patterns and relationships in an intuitive and understandable way. They play a vital role in data analysis, providing insights that are often difficult to discern from raw data or traditional numerical representations. Visualization is crucial for understanding complex data patterns and relationships, and we will introduce the 11 most important and must-know charts that help reveal the information in the data and make complex data more understandable and meaningful. 1. KSPlotKSPlot is used to evaluate distribution differences. The core idea is to measure the maximum distance between the cumulative distribution functions (CDF) of two distributions. The smaller the maximum distance, the more likely they belong to the same distribution. Therefore, it is mainly interpreted as a "system" for determining distribution differences.
