output F-values and Chi-square values in DataAudit.

Currently, when the response variable is continuous and the predictor variables are also continuous, correlation coefficients, T-values, and importance are available in DataAudit. Sorting by correlation coefficient makes it easy to find variables with high correlation.
I would like to do the following similarly:

1. For combinations of continuous and categorical variables, output the F-value and importance.
2. For combinations of categorical variables, output the Chi-square value and importance.
3. For continuous variables, sorting by importance is possible, but decimal points seem to be truncated, so even when degrees of freedom are the same, the order does not follow the T-value. Please ensure correct sorting.

In all cases, sort by importance to identify features that have the greatest impact on the response variable and display a graph.
In Feature Selection, it is possible to display a ranking of important predictor variables, but statistical values are not shown and no graph is displayed. I want to discover important variables while viewing the graph.
