1. Introduction With the outbreak of COVID-19 in 2020, epidemic prevention capabilities have become a hot topic worldwide. Cities need to improve their ability to prevent epidemics by analyzing various factors that may affect their performance. In this paper, we use R language software and multivariate statistical analysis methods to analyze the epidemic prevention capability of cities in eastern China.

2. Variable Selection and Data Sources The variables used in this study are collected from multiple sources such as government statistics websites and academic journals. The variables include population density, medical resources per capita, air quality index (AQI), GDP per capita, etc.

3. Problem Analysis Based on Clustering Analysis Method Using clustering analysis method to group cities with similar characteristics together can help us understand the commonalities between them. We can then identify which factors contribute more significantly to epidemic prevention capability.

4. Problem Analysis Based on Factor Analysis Method Factor analysis is an effective method for exploring the underlying structure of complex data sets. By using factor analysis method to reduce the dimensionality of data and extract common factors that explain most of the variation between variables, we can identify key indicators that contribute most significantly to epidemic prevention capability.

5. Problem Analysis Based on Multiple Regression Analysis Method Multiple regression analysis is a widely used method for predicting outcomes based on multiple independent variables. By using this method, we can build a model to predict the epidemic prevention capability of cities based on various factors such as population density, medical resources per capita, AQI, GDP per capita, etc.

6. Conclusion and Recommendations In conclusion, this paper analyzes the epidemic prevention capability of cities in eastern China based on R language software and multivariate statistical analysis methods. Through clustering analysis, factor analysis, multiple regression analysis, and other methods, we provide insights into the factors that affect epidemic prevention capability in eastern China. We recommend that cities should pay more attention to factors such as medical resources per capita and air quality index when improving their epidemic prevention capabilities.
