I am new to time series and therefore trying to feel my way around. I am required to do some analysis and possibly come up with a model. However, I have at most 2 years worth of quarterly data (at most 8 datapoints). Can I build any meaningful model based on the data? What possible model apart from linear regression with time as regressor can be built?

Thanks

1Not really. Eight data points wouldn’t even be enough for simple ordinary least squares regression, or even a t-test. I’d like to ask, what is it that you are trying to accomplish? What is your research question? – Jon – 2018-08-02T05:20:23.160

A

graphwould be useful (no need of the units). If you follow Tuker's advice, data visualization should become an automatic reflex. – AlainD – 2018-08-02T11:05:57.177
