`model:`	List, output from dualtraj or dualtrajMS
`X1:`	Matrix, design matrix for series 1. 1st column should be the id.
`X2:`	Matrix, design matrix for series 2. 1st column should be the id.
`y1:`	Vector, outcomes for series 1
`y2:`	Vector, outcomes for series 2
`z1:`	Matrix, K1 x dim(X1)[2] indicator matrix indicating which variables to inlcude in each group.
`z2:`	Matrix, K2 x dim(X2)[2] indicator matrix indicating which variables to inlcude in each group.
`burn:`	float, fraction of draws to keep for post burn-in period.
