Hi, im currently trying to finish my dissertation but at last minute found out that I can't use my university software to run interrupted time series analysis. Im looking at the effects of the London 2012 olympics on house prices. I have 6 years for pre and 6 years for post. My dependent variable is HPI and independent variables are population size, employment level, GDP and GDHI per head. I the same data for my control group which is the city of greater manchester. I don't know what to do and I only have a few days left to submit. I really need help in running the analysis. I struggled to understand how to actually test autocorrelation and these other things. Please I need help!!!
I have attached the excel sheet with my data that im using if that will help more.

A few days is not going to be enough. Be proactive and contact your dissertation committee and tell them what is going on.
It appears that you have panel data, so if you have access to the ETS software in SAS, you could look at PROC PANEL. If you have access only to BASE SAS and SAS/STAT, I don't think you will be able to write all the code necessary to do an interrupted TS analysis in time. You may need to consider other analysis platforms (R, Julia, etc.) but finding the correct package, and some good examples, will be the difficult part.

You might use PROC MIXED for this. This paper has some information and examples:

Not directly, no.
I encourage the OP to work with their dissertation advisor, faculty, and university resources to plan an effective analysis. The advisor should be able to suggest methods and software that are appropriate to the research plan.
