Ways to Preprocess Data

After you import the estimation data, as described in Import Data (GUI), you can perform the following preprocessing operations using the Data Preprocessing Tool in Simulink® Design Optimization™ software:

  • Exclusion — Exclude a portion of the data from the estimation process. You can exclude data by:

    • Selecting it with your mouse.

    • Graphically by selecting regions on a plot.

    • Using rules, such as upper or lower bounds.

  • Handle missing data –– Remove missing data, or compute missing data using interpolation.

  • Handle outliers –– Remove outliers.

  • Detrend — Remove mean values or a straight line trend.

  • Filter — Smooth data using a first-order filter, an arbitrary transfer function, or an ideal filter.
