Hi,

I know this question has been asked several times, but it's worth asking again.

Is it right to perform PCA analysis with dummy (0/1) variables?

I used to code :

factor radio tv frige bike moto car , pcf factor(5)

where radio tv ... are dummy (0/1),

but a colleague just told me I am wrong.

A MCA in his mind is better.

What is the best command in that case? Just to make sure.

Best regards.

Amadou.
