How do I calculate distance between new cases and PCA model datapoints using PCA1 and PCA2 values
I created a simple PCA model with 2 components PCA1 and PCA2 from 3 variables of 40 objects. From very helpful guidance here, the model set was given weight=1 so that the location of new cases (weight=0) could be visualized relative to the model objects. Question: Is there a way to find the distance between the new objects (n=51) and each of the 40 model set objects? I found an add-in for image ...
