For a single unit group, the multiplicative model of dChip 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.
