New to SQL Server 2008 Microsoft Time Series algorithm improved ARIMA plus ARTxp method, and a blending algorithm = better results New prediction mode allows adding new data to time series models Holdout Support added Easily partition data into training and test sets that are stored in mining structure & available to query after processing Ability to build mining models based on filtered subsets added Results in less structures, i.e. can just filter existing Drillthrough functionality extended makes all mining structure columns available, not just columns included in the model allows you to build more compact models Cross-validation added allows users to quickly validate their modeling approach by automatically building temporary models and evaluating accuracy measures across K folds. The feature is available through a new cross-validation tab under Accuracy Charts in BIDS, in addition to being accessible programmatically via a stored procedure call.

Microsoft Time Series algorithm improved

ARIMA plus ARTxp method, and a blending algorithm = better results

New prediction mode allows adding new data to time series models

Holdout Support added

Easily partition data into training and test sets that are stored in mining structure & available to query after processing

Ability to build mining models based on filtered subsets added

Results in less structures, i.e. can just filter existing

Drillthrough functionality extended

makes all mining structure columns available, not just columns included in the model

allows you to build more compact models

Cross-validation added

allows users to quickly validate their modeling approach by automatically building temporary models and evaluating accuracy measures across K folds. The feature is available through a new cross-validation tab under Accuracy Charts in BIDS, in addition to being accessible programmatically via a stored procedure call.
