00010 THESE ARE INSTRUCTIONS FOR USING THE DESCRIPTIVE STATISTICS
00011 PROGRAM 'DESTAT*'. THIS PROGRAM ANALYZES A SET OF OBSERVA-
00012 TIONS ON ONE VARIABLE. OUTPUT CONSISTS OF SUMMARY STATISTICS,
00013 AND (OPTIONALLY) THE FOLLOWING: ORDER STATISTICS, FREQUENCY
00014 AND CUMULATIVE DISTRIBUTIONS, DATA ARRANGED IN ASCENDING ORDER.
00015 THE PROGRAM WILL ASK WHETHER THESE ARE WANTED, AT RUN TIME.
00016 THE USER CAN CONTROL THE CLASS INTERVAL USED FOR THE FREQUENCY
00017 DISTRIBUTIONS, BY SPECIFYING ANY TYPICAL CLASS INTERVAL. THIS
00018 IS DONE BY SUPPLYING TWO NUMBERS, THE LOWER AND UPPER LIMITS OF
00019 THE TYPICAL CLASS. IF NO TYPICAL INTERVAL IS SPECIFIED, THE
00020 PROGRAM WILL CHOOSE AN APPROPRIATE NUMBER OF CLASSES (USING
00021 STURGES' RULE) AND GENERATE CONVENIENT CLASS LIMITS AND A CLASS
00022 WIDTH ACCORDINGLY. DESTAT* PROVIDES AS PART OF THE ORDER STAT-
00023 ISTICS OUTPUT THE MAIN PERCENTILES OF THE DISTRIBUTION, BUT THE
00024 USER CAN OBTAIN AS PRINTOUT ANY OTHER PERCENTILES DESIRED BY
00025 ENTERING THEM AS INTEGERS (E.G., 70 FOR THE SEVENTIETH PERCENT-
00026 ILE.). TO USE THE PROGRAM, TYPE THE FOLLOWING:
00027
00028 200 DATA X(1), X(2),...., X(N) (THE VARIATES TO BE DESCRIBED)
00029 (DATA MAY BE CONTINUED ON LINES 201-398)
00030 400 DATA L, U (A TYPICAL CLASS, L=LOWER LIMIT, U=UPPER)
00031 500 DATA P1, P2, .... (ADDITIONAL PERCENTILES DESIRED)
00032 RUN
00033
00034 NOTE: DESTAT* COUNTS THE NUMBER OF VARIATES SUPPLIED. LINES 400
00035 AND 500 ARE EACH OPTIONAL INPUT. NOTE ALSO: FOR A LARGE NUMBER
00036 OF VARIATES, THE SORT TIME IS THE MAJOR CONTRIBUTOR TO RUNNING
00037 TIME, HENCE THE FULL OUTPUT OF THE PROGRAM IS PRINTED AFTER
00038 THE SORT IS COMPLETED.
