Answer #1

Factor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors

. For example it is possible that variations in six observed variables mainly reflect the variations in two unobserved (underlying) variables.

Factor analysis searches for such joint variations in response to unobserved latent variables. The observed variables are modelled as linear combinations of the potential factors.

Factor is linear combination of variables

Answer:- a linear combination of variables

in most of the data analysis cases, the “reducing factor” n which lowers the number m of dimensional variables to m-n dimensionless groups, exactly equals the number of relevant dimensions (M, L, T). In one case this was not so. Explain in words why this situation happens.
