nag_tsa_transf_orders (g13byc) allocates memory to the four pointers in the structure of type Nag_TransfOrder. The structure is used to hold the transfer function model orders of the input series for some functions in Chapter g13
. This function must
be called before any attempt is made to access this structure.
The transfer function model orders of the input series are supplied to the time series function in memory allocated to four pointers. These pointers are the constituent members of the structure of type Nag_TransfOrder used by some functions in Chapter g13
The purpose of nag_tsa_transf_orders (g13byc) is to allocate memory to these four pointers.
