This program combines a spreadsheet, simple scatter plot, multiple linear and nonlinear regression analysis capabilities. It operates on a matrix of up to 20 columns of data, each of which can have up to 500 rows (observations). Data can be read from the terminal (TTY) or from disk files. Reading is freeform. Data may be written to the terminal or to files, in user-designed formats. Standard and conditional transformation can be carried out with algebraic expressions. Linear regression can be performed, in a user-guided fashion, using the sweep algorithm. Nonlinear regression can be carried out with the FIT command. The sequential SIMPLEX is used for error minimization, in this case. FORTRAN 77 (Microsoft FORTRAN) Lines of Code: 3900 |
