an object created by blrm
integer specifying which intercept to fetch
specifies the result to return
matrix with number of raws equal to the numnber of original draws
Fetches matrix of posterior draws for partial proportional odds parameters (taus) for a given intercept. Can also form a matrix containing both regular parameters and taus, or for just non-taus.
