I study the impact of banking regulations on the stability and efficiency of Islamic banks compared to traditional banks cases of Mauritania.

I want to use the comparative analysis of Charles RAGIN in my thesis I have as variable depands (stability and efficiency) and explanatory variables (capital ratios, liquidity and leverage).

I have the data for 15 banks for 10 years the problem is the dichotimization of the variables to build the truth table.

Thank you
