C PROGRAM XTAB
C
C DESCRIPTION
C THIS PROGRAM CROSS-TABULATES PAIRS OF VARIABLES (WITH OR WITHOUT
C A CONTROL VARIABLE) GIVING FREQUENCIES, PERCENTAGES, OR OTHER
C STATISTICS DESIRED BY THE USER.
C
C SOURCE
C NORMAN W. JOHNSON, DEPARTMENT OF MATHEMATICS, WHEATON COLLEGE,
C NORTON, MASS.
C
C INSTRUCTIONS
C THE USER MAY ENTER OR ANALYZE DATA BY GIVING ONE OF THE COMMANDS
C "INPUT", "OUTPUT", OR "ZERO" OR MAY TERMINATE THE EXECUTION OF
C THE PROGRAM BY TYPING "STOP".
C
C THE COMMAND "INPUT" (OPTIONALLY FOLLOWED BY THE TABLE SIZE) EN-
C ABLES THE USER TO ENTER A HYPOTHETICAL FREQUENCY TABLE FOR TWO
C OR THREE VARIABLES TO BE CROSS-TABULATED. ONE OR MORE OUTPUT
C OPTIONS MUST BE SELECTED AND THE APPROPRIATE CODE NUMBERS EN-
C TERED. THE FOLLOWING OPTIONS ARE AVAILABLE:
C 1--FREQUENCY OF RESPONSES
C 2--PERCENTAGES ACROSS
C 3--PERCENTAGES DOWN
C 4--PERCENTAGES OF TOTAL
C 5--CHI-SQUARE, DEGREES OF FREEDOM, AND PROBABILITY
C 6--GOODMAN AND KRUSKAL'S TAU
C 7--YULE'S Q OR GOODMAN AND KRUSKAL'S GAMMA
C 8--PHI COEFFICIENT OR KENDALL'S TAU
C 9--SOMER'S D
C
C THE COMMAND "OUTPUT" PERMITS THE USER TO KEEP THE DATA OF THE
C LAST CROSS-TABULATION BUT TO CHANGE THE OUTPUT OPTIONS.
C
C THE COMMAND "ZERO", GIVEN AFTER A CROSS-TABULATION INVOLVING A
C CONTROL VARIABLE, PRODUCES THE CORRESPONDING ZERO-ORDER STATIS-
C TICS.
C
C AFTER ANY OF THE ABOVE COMMANDS IS CARRIED OUT, A NEW COMMAND
C MAY BE GIVEN. THE USER MAY SUPPRESS THE PRINTING OF TABLES OR
C ANY OTHER OUTPUT IN ORDER TO GIVE A NEW COMMAND IMMEDIATELY BY
C TYPING <CTRL>O AND PRESSING <RETURN>. FURTHER EXECUTION OF A
C COMMAND MAY BE HALTED AT ANY BREAK POINT BY TYPING "ABORT".
C
C WHENEVER THE USER IS EXPECTED TO GIVE A COMMAND OR TO PROVIDE
C CERTAIN INFORMATION NEEDED FOR THE EXECUTION OF A COMMAND, AN
C EXPLANATION OF WHAT IS REQUIRED MAY BE OBTAINED BY TYPING THE
C WORD "EXPLAIN" OR SIMPLY A QUESTION MARK.
C
C THIS PROGRAM ASSUMES THAT OUTPUT IS TO THE USER TERMINAL. IF
C OUTPUT TO A FILE ON THE DISK IS DESIRED INSTEAD, THE DISK SHOULD
C BE ASSIGNED LOGICAL UNIT 5 PRIOR TO RUNTIME.
C
C REMARKS
C THE COMPUTED VALUE OF CHI-SQUARE WITH ONE DEGREE OF FREEDOM
C INCORPORATES A CORRECTION FOR CONTINUITY. THE CALCULATION OF
C CHI-SQUARE IS ACCOMPANIED BY A WARNING IF THE EXPECTED FREQUENCY
C IS LESS THAN 1 IN ANY CELL OR LESS THAN 5 IN MORE THAN 20 PER
C CENT OF THE CELLS. KENDALL'S TAU HAS A CORRECTION FOR TIES.
