True. Since my data are readership hits, I populated the days without readership hits zero. 

I was thinking somewhere in the line where in a real research, you will have missing values. Say, you are trying to identify the income solely based on education. If you pick 25 ppl for the research and you know the incomes of all 25 ppl but education of only 24 ppl. You would have a missing value unless you decide to ignore it all and take 24 ppl for your research. How would you do regression in this case where you decide to include all the ppl and hence have a missing value. 

 

Thanx
