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:
