SAS Enterprise Miner

[deleted_user]

Hi All,

I am doing regression model in SAS Enterprise Miner. I am building lagged regression model in it. The problem is that in lagged regression model the current value of the dependent variable depends on the past values of it and so the the first row of the lagged explanatory variables contain nothing or are null. the SAS assumes these variables as numeric and I am unable to enter these variables in the model.

Could you suggest what is the way out?Di I make all the series (dependent an explanatory series starting from the same row , that is, do I level each series since if I add '0' in each non empty cell that will not be right as i have checked that it gives different statistical resuls.

Kindest Regards,
Mark

Hi:
There is a special forum, set up just for data mining (with SAS Enterprise Miner) and text mining (with SAS Text Miner). Perhaps your question will reach Enterprise Miner folks if you posted it there:
