Subject: How to compare subsequent values in a column?
How to do a simple ratio calculation << row2 value/row1 value >> and so
on
for the whole data set?
The next aspect of my problem relates to doing this ratio calculation
for
a
varying number of grouped observations. If there are many groups in the
data and each group has several rows and the number of rows do not
match,
how we can do it then. I can try to work around the second issue, but
would
need some quick help for the first issue.
