Details

Some calculations involve a matrix inversion step. The method argument specifies which method should be used for calculating the inverse. See matsbyname::invert_byname().

method_q_calculation specifies the method with which the q vector should be calculated. Default is "sum_U_Y_rows", corresponding to a demand-sided view of q. Alternatively, an analyst can choose to use the "sum_R_V_cols" method, corresponding to a supply-sided view of q. In the case of a balanced ECC, the method does not matter.

Input-output matrices can be calculated for either an upstream swim (demand-sided as Leontief) or a downstream swim (supply-sided as Ghosh). The direction argument defines the direction. Different IO matrices are calculated based on direction. The default is "upstream", meaning that an upstream swim is desired. Note that "upstream", "demand", and "Leontief" are synonyms. "downstream", "supply", and "Ghosh" are synonyms.

Value

A list or data frame containing input-output matrices.
