hi i'm new to mathematica. and have some background in using other products like minitab and sca for creating models in statisitcs. i am interested in understanding how one might create models against different sequential subsets of data. the application is time series forecasting. first i'd like to create a model to fit data points 1..100, then see its accuracy against points 100..125. then create a model for points 26..125 and see its accuracy against points 126..150. and repeat this successively. how might one do this in mathematica? i have just started looking through all the vast sections in here and there are lots. so i'm just asking for direction - which modules to load if any, what programming constructs to use, which say 3 sections of the documentation would get me started, any hints about how to get the data into groups that can be easily worked with for this application. thanks for your help.
