cov.mnp: Extract Multinomial Probit Model Covariance Matrix


cov.mnp is a function which extracts the posterior draws of covariance matrix from objects returned by mnp.


  cov.mnp(object, subset = NULL, ...)



An output object from mnp.


A scalar or a numerical vector specifying the row number(s) of param in the output object from mnp. If specified, the posterior draws of covariance matrix for those rows are extracted. The default is NULL where all the posterior draws are extracted.


further arguments passed to or from other methods.


When a numerical vector or NULL is specified for subset argument, cov.mnp returns a three dimensional array where the third dimension indexes posterior draws. When a scalar is specified for subset arugment, cov.mnp returns a matrix.
