Dissertation question - correlation/cointegration
Posted: Tue May 26, 2009 9:46 am
Dear all,
for my thesis I am looking at the relationship between an equity index and a few other indices which are not equity based. I intend to look at the correlation between them which is fine however, I am not sure how to go about looking into cointegration as I am fairly new to stats and am doing this study upon reccomendation from my supervisor.
I understand that I need to make sure the data is stationary and to look at the t-1 residual plots to do this. I know this is probably an extremely basic question, but could somebody please explain the steps in lay-mans terms for me?
Just to clarify, I have quarterly returns for each index over a 25 year period and also have the rebased data started at 100 for each index. So in addition to carrying out cointegration on the data set, I would like to know whether you think I should regress the quarterly returns, the rebased index, or a log of the index?
I really appreciate any help :-)
Thanks,
Adam
