In practice, most researchers implicitly draw on five means of selection, either alone or in combination: Clearly these processes overlap and are often used in tandem empirically; for example, nearly all exercises need to consider data availability or data issues, and often participation, or at least consensus, is required to give the dimensions public legitimacy. Generally, we can measure different indices through MS-Excel. But it needs to understand the formula of the index (FGT index). Just entrythe infor b.
