What is the difference between Zeroes and Nulls in NAMSR?

For the purposes of NAMSR, zero and null values are the same. NAMSR has collected and processed ALL AV-3M and price data for the past 5 years and any zero or null values indicate that there were no Costs, Counts, or Hours associated to that specific WUC, TEC, TMS, TM, or FY. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
