Contemporaneous Correlation Demystified: Know the Techniques

[@abdullahbinomar3390]

Thanks 👍
I also request you to make videos on second generation panel data modelling techniques such as MMQR model, Q&Q regression, bootstrap methoed etc...

[@CrunchEconometrix]

Thanks for your suggestions, Abdullah. Videos on QR are published on my Teachable paid platform.

How do we calculate contemporaneous correlation in the case of time series data? I have time series data from April 1996 to August 2021, and I want to calculate the contemporaneous correlation structure of the series.

Unfortunately, I have no idea. You may want to check out other online resources. Thanks.

Contemporaneous correlation does not occur in time series data.
At a given time t*, x(t*) and y(t*) are just 2 values of 2 variables, for example x(t*) = 1 and y(t*) = 2. Here is only ratio (2 or 1/2), no correlation.
If you are interested in correlation between time series, simply calculate the correlation coefficient between them.

In time time series, does it mean correlation at lag 0?

[@CrunchEconometrix]

I'm unable to understand your question. Kindly rephrase.

@@CrunchEconometrix does contemporaneous correlation between two time series means the simple correlation between the series at lag 0?
