 BAlGOL 

 COMPUTER - IBM 1620 



DIFFERS FROM PREVIOUS TREND-SURFACE PROGRAM FOR THE IBM 1620 (SPECIAL 

 DISTRIBUTION PUBLICATION 14, BY D.I. GOOD, 1964) IN ONE MAJOR ASPECT — 

 DATA ARE NOT STORED IN A DIMENSION ARRAY WITHIN THE COMPUTER, BUT ARE 

 PROCESSED AND ACCUMULATED AS READ IN. THE PROGRAM, THEREFORE, IS THE- 

 ORETICALLY CAPABLE OF INCORPORATING AN INFINITE NUMBER OF DATA POINTS. 

 PRODUCES VALUES UP TO THE FOURTH-DEGREE EQUATIONS. STORAGE RtQUIRE- 

 MENTS — APPROXIMATELY 18K BITS. RUNNING TIME — TWO PASSES ARE NECESS- 

 ARY, REQUIRING ABOUT 12 MINUTES PER 100 DATA POINTS ON EACH PASS. AU- 

 THORS — ROBERT J. SAMPSON AND JOHN C. DAVIS, IDAHO STATE UNIV. REF. —
