stepi3 function

Component matrices from the Tucker3 decomposition

The function computes the component matrices from the Tuckals3 algorithm.

stepi3(param)

Arguments

• param: The weighted contingency table and the matrices of the row, column and tube components derived via the Tucker3 model.

Details

The functions newcomp3, stepi3, init3 and step.g3 compute the component matrices and core array in the iterative steps of Tuckals3. They are all utilised from the function tucker.

Returns

Component matrices from the Tucker3 decomposition.
