Fit MOM-SS (MOM-SS / BFR.BE backend)

This is a thin wrapper around BFR.BE::BFR.BE.EM.CV() (or similar entry points). Because the upstream API may evolve, we keep this wrapper flexible:

• If you pass ... with X and M (the membership matrix), they are forwarded.

• If you pass Y_list, we will stack it and construct X and M accordingly.

Usage

fit_momss(
  Y_list,
  k,
  X = NULL,
  scaling = FALSE,
  center_within_study = TRUE,
  folds = 10,
  ...
)

Arguments

Y_list

Optional list of study matrices. If provided, we create a stacked matrix.

k

Positive integer number of shared factors.

X

Optional covariate matrix or list of covariate matrices aligned to Y_list.

scaling

Logical; whether to scale the data.

center_within_study

Logical; whether to center each study's data before fitting. Recommended unless you have strong reasons not to.

folds

Number of folds for cross-validation within MOM-SS.

...

Parameters that can be pass directly to BFR.BE::BFR.BE.EM.CV().

Value

A bifa_fit object.
