The first update of the Yellow River water and sediment monitoring data analysis ideas and code for Question E of the 2023 National Mathematical Modeling Competition

2023 Mathematical Modeling E Questions First Update

Question  1  : Study the relationship between the sediment content of the Yellow River water at this hydrological station and time, water level, and water flow, and estimate the watersix 

The annual total water flow and annual total sediment discharge of the station.

1. Data preprocessing: data cleaning, missing value processing
2. Correlation analysis and regression analysis were used to study the relationship between sediment content and time, water level, and water flow. Consider building a multiple regression model.
