Missing values
Posted: Wed Mar 14, 2012 10:06 am
Hi,
I am Mathias student international business. I have a question concerning the editing of the data that I've collected.
I'm using the Eviews edtion 7 and I have a small question concerning the editing of the sample.
In my dataset (panel data), I only want to use positive observations (values), therefore I've indicated in my sample that for example: profitmargin>0 and laborproductivity > 0, ....
The question where I'm strugling with is the fact that my data also has observations, wherefore the data isn't available for (= missing values).
Do I have to filter my dataset also for these missing values, or are they automatically filtert out?
Thanks in advance!!
Mathias
