Table 2. Cell type-specific expression coefficients^* for Egr transcription factors in relapse and non-relapse prostate cancer (n = 108 arrays).

		βj relapse	βj non-relapse	γj	Probability γj *
Egr3	Tumor	−0.796	1.125	−1.921	0.023
	Stroma	2.638	1.783	0.856	0.272
	BPH	−0.601	−8.409	7.808	0.365
Egr1	Tumor	−1.088	−0.304	−0.784	0.017
Egr2	Tumor	0.072	0.994	−0.923	0.139

^*Probabilities of β_j were all <0.05 and are not shown; equations for calculating β_j are defined in the Materials and Methods. βj are expressed relative to the mean expression of all probe sets of the array.
