The model must come from the investigator, not from the data.
Data only helps to choose between models, estimate parameters,
and related questions.
You have very little data, in fact, on which to make such
decisions. Even estimating the parameters from a four-factor
model with only 20 observations is poor unless the random
variation is very small. You will have to essentially use
your prior theory.
