It is not a question but more than a direction and advise, Please if you can guide me/ give me and idea to start with

This is a small research, not a big one just to run a multiple regression, and interpretation of the result:

1.Please choose a specific dependent variable of interest

2.Please collect the data for at least 10 years on it . Example GDP US, Life expectancy men, etc.,

3.Find at least 4 to 6 variables that you think are good predictors of the dependent variables and collect data on them

I can do later on the requested analysis which are:

Run the plots of the dependent variables VS each of the variables. 2. Run the regressions as you see fit 3.include and remove variables based on the t tests of each variable.
