Preparation for strustural path analysis from plain text input output matrix

Abstract

We are dealing with a matrix of the size 136 (formerly 79) known as financial social accounting matrix (FSAM). Inside a financial SAM is a square matrix of 107 rows times 107 columns sub set known as SAM. We are augmenting a command line based software for more functionality. The addition from us includes: data base for the output, bar chart output, table generation, graphical presentation of path. Users want more versatile input not just single proprietaty plain text format. We take over preparing tedious input such as : moving exogenous rows to bottom side of matrix, error prone command line typing, filling blanks with zeroes, serial numbering of rows, separation of numbers and names. This is presented graphically with a model called use case.
