function iduibn(arg,nu,ny)
%IDUIBN Handles model estimation for model that are defined By Name.
%   NU and NY are the number of inputs and outputs in the data set.
%   The argument ARG takes the following values:
%    open  Opens the dialog box
%    close Closes the dialog box
%   All estimation is handled by IDUIIO.
