Dear R users,

I'm wondering about the singular.ok option in lm. If singular.ok is set to TRUE does it mean that we allow the generalized inverse of (X'X)^-1 (where X are the independent variables and ' denotes the transpose)? Or is the singularity handled in some other way?

Thank you!

Best regards,

Martin.
