STATPAC(ID:7658/)Interactive statistical system with programmable operators References: STATPAC STATPAC, a lightpen-controlled program for on-line data analysis was developed and used at Decision Sciences Laboratory, Hanseom Field, Bedford, Massachusetts, see Goodenough (1965). The system is designed so that no vocabulary of a language need be learned by a user. This is accomplished by displaying a "menu" of the vocabulary on a computer-driven scope for user'selection. Because it displays on the scope only those items that will make a syntactically correct command, no invalid commands can be generated. The author claims similarity in his objectives and methods to the Culler-Fried systems; however, instead of providing general purpose mathematical operators, STATPAC is oriented toward statistical operations. While composing a command at the console, menus of operands (vector titles) and operations are displayed for lightpen selection. Some of the available operations are: DISPLAY, TYPE, PUNCH, CORR between (X) and (Y), STD DEV OF, MEAN OF, REGRESSION (X) vs (Y), and SUM OF SQUARES OF. The Decision Sciences Laboratory was deactivated in June 1967. STATPAC was in use up to the time the equipment was removed from the laboratory. At that time graphing facilities had been added and were in use for almost two years before the equipment was removed. in [ACM] ACM Computing Surveys 2(4) Dec1970 view details |
