Dear Statisticians,
I have a variable A, variable B and variable C.
Variable A is generated after using principal component analysis (PCA) with three proxy variables.These original proxy variables are discrete, arranging from 1 to 5. However, variable A is arranging from -3 to 2. Variable C and B is a positive and continuous.
My purpose is to test whether variable B moderates the relationship between variable A and variable C.
The above model is simplified one which is convenient for discussion here.
My question: is it allow to test the moderation effect of B on the relationship between A and C, after PCA? Thank you so much.
Best regards,
David

Code:
reg C c.A c.B c.A#c.B, r
