PROGRAM SYSTEM CONSISTS OF A SET OF NEARLY INDEPENDENT SECTIONS FUNC- 

 TIONING ONLY WHEN CALLED BY THE 'MAIN' PROGRAM. THE USER ENTERS A 

 CURVE INTO THE 360/40 VIA A RAND TABLET AND INTERACTIVELY TO SPECIFY 

 VARIOUS WAYS OF FITTING, EDITING AND DISPLAYING THE CURVE ON An IBM 

 2250 SCOPE. THE LAST STEP OUTPUT IS PUNCH CARDS WITH DATA POINTS. OR 

 COEFFICIENTS. THE SYSTEM FOR IBM 360 ALONG WITH THE PACKAGE OF GRAPH- 

 ICS USED AT RAND TAKE UP ROUGHLY ONE-HAlF OF THE COMPUTER CORt MEMORY. 

 DOCUMENT BY A.S. PRIVER, SEPT 1969. THE DDC NO. IS AD 693 920.

BARTLETTiS METHOD FOR COMPUTING THE BEST VALUES FOR FITTING A LINEAR 

 RELATIONSHIP OR AN EXPONENTIAL RELATIONSHIP. THE 70 0/0 AND 90 0/0 

 CONFIDENCE LIMITS ON THE SLOPE ARE ALSO FOUND. THE PROGRAM tAkES A

CALCULATING AND PLOTTING TIME-TREND CURVES LANGUAGE - FORTRAN,, FAP 



COMPUTER - IBM 7090/94 



COMPUTES AND PLOTS A SERIES OF SMOOTHED OR GRADUATED CURVES BASED ON A 

 SEQUENCE OF GEOLOGIC OBSERVATIONS. NINE SMOOTHING FORMULAE ARE USED 

 WHICH CORRESPOND TO CYCLES OF INCREASING MAGNITUDE WITHIN THE DATA, 

 FOR EACH OF TEN VARIABLES WITH UP TO 500 OBSERVATIONS PER VARIABLE. 

 LEAST SQUARES ANALYSIS IS USED TO FIT A SERIES OF 3RD ORDER POLYNOM- 

 IALS TO THE DATA. STORAGE REQUIREMENTS — 24,757 LOCATIONS. RUNNING 

 TIME — ABOUT 2 MINUTES TO COMPUTE ALL NINE CURVES FOR 100 ObStRVATlONS
