Arguments

x

an object of class mixmod or mdmixmod.

...

currently unused.

Details

These functions provide convenience reporting for objects of class mixmod or mdmixmod: assignment returns the vector of most probable component assignments; design returns the design matrix, that is, a binary matrix of which the (n,k)th element is 1 if the nth datum is assigned to component k, otherwise 0; iter returns the number of iterations used to fit the model; posterior returns the posterior probability matrix; stats returns a vector of model statistics. Note that in the case of mdmixmod objects, “components” refers here to the top-level classification, that is, Y_0.

Value

A numeric matrix, vector, or scalar.
