SALib.analyze.dgsm：返回参数vi和dgsm的定义是什么？

问题描述

我想对Python中给定的输入和输出数据实施敏感性分析（SA）。输入参数的设计基于sobol序列，因此我决定使用SALib的SALib dgsm模块（基于导数的全局灵敏度度量）并将其与Sobol SA的结果进行比较，但是我找不到一些清晰的文档正是返回参数vi和dgsm的含义。

有人知道这个定义，从而如何理解salib.dgsm SA的结果？它们与Sobol SA有何关系？

public class MainActivity extends AppCompatActivity {

    private boolean isFullScreen;

        super.onCreate(savedInstanceState);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

            getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
        }

        View decorView = getWindow().getDecorView();
        decorView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

        decorView.setOnSystemUiVisibilityChangeListener
                (new View.OnSystemUiVisibilityChangeListener() {
                    @Override
