推定のためのデータの選択

データのサブセットの選択、推定および検証データの指定

関数

`fselect`	FRD モデルの周波数点、または範囲の選択
`getexp`	複数実験データセットからの特定の実験の取得
`merge (iddata)`	Merge data sets into iddata object
`fcat`	周波数領域に沿って FRD モデルを連結

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.
複数実験データおよび結合モデルの処理
この例では、System Identification Toolbox™ を使ってモデルを推定および調整するときに、複数実験および結合モデルを処理する方法を説明します。
