Table 2.

Run time (in hours) for each model

Prior	Model II	Model III	Model IV
${\pi }_j=0.50$	6.01	5.33	3.17
${\pi }_j=0.05$	5.37	5.44	2.93
${\pi }_j\sim \text{Beta}(1,19)$	5.40	5.33	3.02
${\pi }_j\sim \text{Beta}(0.01,0.19)$	6.58	6.53	3.54

Model I does not include the variable selection indicators hence there was no prior for ${\pi }_j$. The run time for Model I was 2.1739 h
