Hi,
I have a quick question about standard deviation in SAS.
Assume that I have the following dataset:
Time Value
1 25
2 32
3 23
4 26
I want to compute standard deviation of between two rows. It implies that I will have the following dataset:
Time Value Stddev
1 25 .
2 32 stddev(25;32)
3 23 stddev(32;23)
4 26 stddev(23;26)
Thanks in advance for help!
data have;
input Time Value;
stddev=std(value,lag(value));
cards;
1 25
2 32
3 23
4 26
