For a single unit group, the multiplicative model is:
$$y_{ik} = \theta_i \phi_k + \varepsilon_{ik}$$
where $\theta_i$ are the chip effects for arrays $i=1,...,I$,
and $\phi_k$ are the probe affinities for probes $k=1,...,K$.
The $\varepsilon_{ik}$ are zero-mean noise with equal variance.
To make to parameters identifiable, the constraint
$\prod_k \phi_k = 1$ is added.
