Data Preparation

R2026b

Import and prepare data for analysis

Use the MBC Model Fitting app to import data from external file formats and utilize plotting tools to gain an initial understanding of data quality. Clean the data by applying filters or performing manual inspection as needed. Finally, organize the data by operating points to prepare it for further analysis. After preprocessing the data, select the data to use for model fitting. See Select Data for Modeling Using the Fit Models Wizard.
