This assignment involves conducting a panel data regression analysis on the relationship between Fintech and healthcare in GCC countries, using data from The World Bank and potentially filling in missing data or finding alternative sources.

I need expert help with my research.
Attached is a published paper of what I’m trying to do, but I’m using panel data regression instead.
I have downloaded data concerning GCC countries to examine Fintech in Healthcare in the region from The World Bank. The indicators are: Life Expectancy, FDI, GDP, Infant mortality rate, Number of ATMS, Number of Debit Cards, Number of Internet Users.
However, some countries don’t have data. I’m not sure what to do, whether to substitute with the average or keep it blank. My professor said it might be better if the data were reported quarterly but I couldn’t find them anywhere. If you can find the data yourself, then you can use them instead of what I provided. Preferably examine the data from 2001 – 2021. Bahrain, Qatar, Oman, Kuwait, UAE and Saudi Arabia.
Descriptive analysis and Panel Data regression must be performed but the dataset has to make sense in order for it to be successful.
Please share the SPSS files as well. Thank you.
