Using statistical software to import sample data to estimate the relevant parameters of the theoretical model, The model is modified according to the suggestion information provided by the output report in the running result, and an error term is established The degree of adaptation of the model before and after adjustment is shown in the table. The fit index has good effect, and the fit degree between model and sample data is acceptable, which can be further analyzed. The table shows the standard path between the explanatory variable and the explained variable in the modified structural equation model coefficient, critical ratio () and significance test results of path relation coefficient.
