I have made a sketch of all the possible problems which a regression analysis can face, each problem is listed with its major cause and few of its consequences. Later in future an attempt will be made to address these issues one by one. Have a look at this flow chart below and participate with possible improvements in this chart. Thank you.
Note: Endoeniety is actually Endogeneity
Great chart! Did you have time to adress solutions for the issues?
i have mentioned few solutions like solutions for time series issues and like solutions for cross sectional issues
