Specify Estimation and Validation Data in the App

You should use different data sets to estimate and validate your model for best validation results.

Select Subsets of Data

Select portions of data for identification in the app or at the command line.

Create Data Sets from a Subset of Signal Channels

You can create a new data set in the System Identification app by extracting subsets of input and output channels from an existing data set.

Create Multiexperiment Data Sets in the App

You can create a time-domain or frequency-domain data set in the System Identification app that includes several experiments. Identifying models for multiexperiment data results in an average model.

Create Multiexperiment Data at the Command Line

You can create iddata objects that contain several experiments. Identifying models for an iddata object with multiple experiments results in an average model.

Dealing with Multi-Experiment Data and Merging Models

This example shows how to deal with multiple experiments and merging models when working with System Identification Toolbox™ for estimating and refining models.
