Enhanced support of time series

Post by uniter »

Hello SmartPLS team,

I'm working in Econometrics with time series data, that means the observations are ordered by e.g. months or years. An important aspect is the use of lagged explaining variables. If I want to use lagged variables I have to manipulate the data set by hand with an external editor (shifting the rows up or down and trimming) and read it into smartPLS again, but that work could be included in SmartPLS itself.

Example of an inner model with two LV investments and GDP:

GDP(t)=f(investments(t-4), investments(t-3), investments(t-2), investments(t-1), investments(t))
The GDP of today (t) should be explained by all the investmest from toady(t) till 4 quarters ago (t-4).

It would be quite easy to implement and enhance the usage in econometrics or other sciences that use time series data a lot.

Thanks a lot.
