Hi all,
I have some data in the following format
Time ����X
-5�������� 2
-4�������� 3
-3�������� 2
-2������ ��4
1��������� 1
0������ ���2
1������ ���2
2������ ���1
3����� ����2
4����� ����2
5����� ����1
I need to compute y= Mean(X)/SD(X) for different time windows.
For example,
-5,-4 would be window 1
-3,-2 would be window 2 etc.
My present solution is this ( example for window 1)
Egen a=mean(X) if time>=-5 & time<=-4 (and so on for all the different
windows)
Egen b=sd(x) if if time>=-5 & time<=-4 (and so on for all the different
windows)
Gen y=a/b
Is there an easier way to do this???
Thanks very much
Regards
rajesh
