2.3.3 Partial correlation analysis
Soil wind erosion is affected by a variety of factors, and the relationships between multiple factors are complicated. This study used a partial correlation analysis, assuming other independent variables remained constant, to examine the correlation between an independent variable and the dependent variable. It aims to exclude interference by other factors so that the results reflect the influence degree of an independent variable on the dependent variable (Schielzeth, 2010). For example, if there are three sets of variables: x, y, and z, then a partial correlation analysis can be used to study the relationship between the variables and is calculated as follows:
