This node inverts the transformation applied by the PCA Apply node. Given data in the space resulting from the PCA reduction is transformed back to its original space. Information that was lost in the PCA reduction can of course not be recovered.


Fail if missing values are encountered
If checked, execution fails, when the selected columns contain missing values. By default, rows containing missing values are ignored and not considered in the computation of the principal components.
Replace PCA columns
If checked, the PCA columns are removed in the output table.
Select all columns containing the principal components of the original data. Usually the default selection should capture all of these.
