Dear All,

This my first time in the forum and I thank you all for the support and help you are providing. I am an economist working with time series data. Many time series are only available at yearly basis and I need to convert them to monthly. I read the techical support however it is very confusing and sometimes not consistent. for example GDP is a flow not stock variable when reading the help menu it I noticed that in the examples given sometimes it uses OBSERVED=TOTAL and sometimes OBSERVED=AVERAGE. My question is which one I should use?

For stock variables such as FOREIGN RESRVES I am not sure how to write the procedure.
1-My first question is to help me with the procedure that should be used for converting flow variables and stock variables
2-my second question is about ratios. For example if I have yearly BUDGET DEFICIT/GDP (RATIO). Can I just convert the ratio to monthly ratios or do I need to convert DEFICIT and GDP separately then find the monthly ratios?

I am really stuck with this and is taking a lot of my time. I hope you can help so that I can move forward in my research.

Regards,

Ismail

Thank you Scott Barry,

I searched all the SAS support website, but it does not really help. It is still not clear as the examples given do not cover all the possible conversion methods.
For example how to convert ratios (A/B) to higher frequency?In this case usually there are 2 possibilities depending on wherther A and B are flows or stocks:


1-A and B are flows
2-A stock, B flow.

I hope someone can help.

Regards,

Ismail
