I am doing my dissertation on the impact of money laundering on the economic growth of Mauritius and will be using the 3 variables' STR,corruption rate and number of crimes 'together to see its relative impact .I have already collected my data.

Can anyone please enlighten me which model and analysis is appropriate for me and which regression method to use.

I am a little confused.As my data is focusing on the overall of Mauritius and not a particular sector,will panel data analysis be suitable?

Panel data analysis consists of both cross sectional and time series..Is it possible to use cross sectional analysis for this case?

If not,which one to use?how to determine which model and regression is appopriate?and steps to do it..thanks
