Saved Principal Components Analysis Variables
The underlying components that are identified from principal components analysis can be used to create new variables. The correlation between these underlying variables and the individual variables used in the analysis are shown in the Rotated Component Matrix.[note 1]
In Displayr, these variables are created by:
- Conducting the principal components analysis (Insert > More (Analysis) > Dimension Reduction > Principal Components Analysis).
- Selecting the resulting output (it will be selected by default).
- Insert > More (Analysis) > Dimension Reduction > Save Variable(s).
- This is typically, but not always, true. It can not be the case if there is missing data or if a non-standard method is used to compute create the saved variables.
