transform data to series

walidos07

Hello,
my data are defined as follows:
Sample T1 T2 T3 T4
S1 s11 s12 s13 s14
S2 s21 s22 s23 s24
S3 s31 s32 s33 s34
Each line is a time series data.
my question:how to transform my data to use series operators such as discrete wavelet transform for each instance s1, s2 and s3.
thank you for your help

Here's an example that you could use as a basis.

This example is really good.

Do you have more examples?

I hardly ever use: "Process Series" because I don't understand how it works.
But it seems really powerful.

Hello

There are a few more examples on my blog

I don't understand how to download those .xml files on your blog.

For reasons I can't remember now, I keep all the files in Google Docs and it's too late to change now.

Keep following the links until you find them.
