Fri, 28 Nov 2014 07:15:49 GMTHi,

This is not a homework question, it's to do with research.

I want to see if there is a pattern to the values (e.g. high numbers in this part of the sequence, low numbers in that part of the sequence, etc) within the groups, and if there is a difference in the patterns between the groups.

The sequences are not normalised, and I'm fairly sure the first thing I have to do is normalise the sequences (e.g. sequence x would become 0.41 0.14 0.16 0.00 0.08 1.00)

Added complications:

The sequences are aligned (by something that is not related to the values of the numbers)

Sequences may be of different lengths (but are close to the same length)

I think that's it. Please ask if I need to clarify anything.

Thanks so much in advance. I'm not a stats person but I have a huge appreciation for how easy it is for a non-stats person to make the wrong assumptions, use the wrong test, draw conclusions that you can't from the data, etc. So I want to be careful.

I was wondering if someone knew how to analyze or determine the percent change over the entire period of time of the graph? Any suggestions would be helpful. Thank you.
