Quick question: suppose I have a variable like this:
N  Var1
1  12
2  45
3  65
100  15
How can I create a new variable whose first observation is the average of 
Var1[1] and Var1[2], second observation is the avaerage of Var1[3] and 
Var1[4], etc. There will be a total of 50 observations for this new 
variable. Thanks in advance!
