The Data Processing and Summaries reports are useful for preprocessing your data prior to fitting a model. There are data cleaning, transformation, and alignment options available in the Data Processing red triangle menu. See Data Processing Report Options. Each time you perform a preprocessing step, the graphs and summary results are automatically updated. You can perform multiple preprocessing steps in sequence. Each step is added to the list in the Steps outline of the Data Processing report. To remove the most recent step, click the Remove Last Step button below the Steps outline.
