https://communities.sas.com/t5/SAS-IML-Software-and-Matrix/question-about-missing-data/m-p/27584#M129 I was tasked to do a panel analysis but unsure how to go forward. I have already obtained the dataset for 112 countries for periods 1980-2005. However, there are some countries/years with missing values. I wanted to use the tscsreg canned procedure so I don't have to program a code [since I'm also not an expert on this]. I just want to do some simple regression analysis. <BR /> <BR /> I learned that there are so many ways to deal with missing data but i'm not quite familiar with analyzing panel data. I read that you can put/treat missing values as "zero" but if I do that it will complicate with my other variables which values are really "zero". When I replaced the missing values with zero, it ran and gave me some results but unsure whether those results are no bias. <BR /> <BR /> really needs help on this one. <BR /> <BR /> thanks for your help.
