## Re: Matrix to Column

Hello,

Many ways to transpose data in SAS.

Here is a datastep solution.

```data have;
input HS \$ Channel \$ Index :\$15. Month_Series :\$3.  M201601 M201602 M201603 M201604 M201605 M201606 M201607 M201608;

## Re: Matrix to Column

To note on that, it is advisable - to make your life programming easier, to normalise that data.  I.e. have one row for each month/year and result:

TIMEPOINT    RESULT

201601           0.9

201602           0.6

...

This makes programming much easier - the structure of the dataset doesn't change each time based on the data (as the months and years is data).  Also keeps the number of columns down to a reasonble size.  You can always transpose this data back up for a report if you need to.

## Re: Matrix to Column

Thank you for your advice. Indeed the real problem is to calculate a compound Index.
For example: I have a Started value of 3,000 for Jan. I need to extend the Series by Months to Dec, with an assumption of a decrease each month by 1.3%.
This is another way of seeing it.
Thank you a lot,

Thank you for your advice. Yes indeed this is a long way of doing something that I believe it can be a lot simpler. I will try to see it in a simple way.

## Re: Matrix to Column

Hi,

I am afraid attaching Excel sheets is not a good idea, I wouldn't download them as they are a security risk.  Please post test data, in the form of a datastep (to avoid us having to type it all out), and an example output of what you want.

## Re: Matrix to Column

Hello,

Apologies for attaching an Excel file. Only because the browser at work is not supported by SAS.

I have received a reply though and it worked perfectly. It's what's I needed.

Thank you very much for your help.
