Linear Regression Analysis

This chapter demonstrates the process of conducting regression analysis using R. Two distinct regression models were developed using data from 837 surface meteorological stations across China in 2020. The first model examined the relationship between air pressure (Prs) and altitude (Alt). The second model, more complex, considered altitude (Alt), air pressure (Prs), temperature (Tem), longitude (Lon), and latitude (Lat) as independent variables to predict precipitation (Pre). Each model underwent thorough verification.
