How do i truncate a series to lie between 0 and 1?
Not sure exactly what you want. "Ratio of change in series" - does this mean
the ratio of changes for each individual item or for the sum of all of them? But in general the formula for a "change" as a rato (i.e. percentage where 1 is equal to 100%) is as follows: (New Value - Old Value)/(Old Value) But note that if the new value is more than twice the old value this may give a ratio greater than 1, which is correct but would violate your statement that you want it between zero and 1. -- - K Dales "Truncation or normalisation" wrote: Hey, I have two series.
