Subject:      How to run a "within sample" forecast in SPSS v17.0.3
Content-Type: multipart/alternative;

Good Morning List,

I am looking for some help on running a within-sample forecast in SPSS v17.0.3.  I am using the PASW Forecasting package and have been trying to do some Time Series analyses, but have so far been unable to do any within-sample tests of my modeling.  Has anyone done this in SPSS and how can I by pass the default settings - these (estimation period) are defaulted to start= "first case" and end = "last case."  I want to use about 70% to 75% of my available observations for a within sample testing for my models and use the remaining 25% for model validation!

TIA
Mike
