I am using three of the Worldwide Governance Indicators (WGI) estimates. They represent broad dimensions of governance for countries. All indicators range from -2.5 to 2.5 approximately. They are expressed in units of a standard normal distribution.
For your information: here is the link to the website: https://info.worldbank.org/governance/wgi/Home/Documents#doc-intro
I want to use these indicators in a panel regression as control variables. All my other variables are not expressed in units of a standard normal distribution. Is it a problem? Do I need to convert the governance indicators (-2.5, 2.5) to another scale (0, 1)? Will the 'econometrics' make sense?
