The M_bh-σ relation takes the basic form:

Problem: β is not well constrained from prior analyses:

• FM has derived 5.27 ± 0.40, 4.8 ± 0.5, 4.72 ± 0.36, 4.65 ± 0.48, 4.58 ± 0.52

• Gephardt has derived 3.75 ± 0.3

A useful statistical analogy: Height vs. Weight! Graph the height and weight of each individual in the room Humans height should scale as power law of 1/3 with weight (based solely on volume)
