Schematic expression patterns. For gene groups b – d (Subfigures b – d) the indicator variables g_n are equal to 0 if the logarithmic expression levels x_n are expected to be similar to x₁ and 1 otherwise (Table 1). The four no-EGF columns are equal to 0 by model assumption 1, and the four EGF columns are equal to the corresponding columns of Fig. 5 by model assumption 2. For gene group a (Subfigure a) the indicator variables g_n are equal to 0 by definition
