TABLE 8.

Performance comparison between the original and the reparameterized methods

	Original		Reparameterized
Coefficient	CPU (hr)	ESS	CPU (hr)	ESS	Relative ESS
α (I = 61)	7.017	9680	3.595	6866	1.38
β (J = 15)	7.017	9045	3.595	6951	1.50

Analyzing the Singh and Rhomberg (1987) data set, the total CPU time was measured for both methods and the effective sample size (ESS) was calculated, as defined in Equation 3. The last column shows the relative effective sample size standardized for CPU run time, indicating the relative efficiency of the reparameterized method over the original method.
