C     PROGRAM CROSS1
C	(DATA ANALYSIS PART OF PROGRAM CROSS)
C
C     DESCRIPTION
C	THIS PROGRAM CORRELATES RESPONSES TO SELECTED QUESTIONS OF A
C	QUESTIONNAIRE TO PRODUCE A TABLE OF MARGINAL FREQUENCIES FOR
C	ANY VARIABLE OR CROSS-TABULATIONS OF PAIRS OF VARIABLES (WITH
C	OR WITHOUT A CONTROL VARIABLE) GIVING FREQUENCIES, PERCENTAGES,
C	OR OTHER STATISTICS DESIRED BY THE USER.  AN EXCLUSION ANALYSIS
C	IS MADE IN EVERY CASE.  AN ITEM ANALYSIS MAY BE CARRIED OUT ON A
C	SELECTED SET OF VARIABLES AND THE RESULTS TABULATED AS A MATRIX
C	OF ITEM INTERCORRELATIONS.  THE USER HAS ACCESS AT ALL TIMES TO
C	EVERY VARIABLE IN THE SURVEY (AS MANY AS 128).
C
C     SOURCE
C	NORMAN W. JOHNSON, DEPARTMENT OF MATHEMATICS, WHEATON COLLEGE,
C	NORTON, MASS.
C
C     INSTRUCTIONS
C	THE CODED RESPONSES TO THE QUESTIONNAIRE SHOULD BE READ FROM
C	CARDS AND WRITTEN INTO AN ASCII DATA FILE BY THE PROGRAM SURVEY.
C	A PRELIMINARY TABULATION OF MARGINAL FREQUENCIES FOR ALL VARI-
C	ABLES THE USER INTENDS TO WORK WITH CAN BE OBTAINED BY RUNNING
C	THE PROGRAM SORTER.  MAPPING OF VARIABLES AND OTHER MANIPULATION
C	OF THE DATA CAN BE CARRIED OUT USING THE PROGRAM CROSS2.
C
C	THE PROGRAM WILL FIRST REQUEST THE USER TO ENTER THE NAME OF
C	THE DATA FILE.  AFTER THIS IS DONE, A DESCRIPTION OF THE SURVEY
C	WILL BE TYPED.  THE USER MAY THEN PROCEED TO ANALYZE THE DATA BY
C	GIVING ONE OF THE COMMANDS "XTAB" OR "ITEM" OR MAY TERMINATE THE
C	EXECUTION OF THE PROGRAM BY TYPING "STOP".
C
C	COMMANDS THAT TAKE VARIABLES AS ARGUMENTS MAY HAVE THE LIST OF
C	VARIABLES ENTERED ON THE SAME LINE AS THE COMMAND.
C
C	THE COMMAND "XTAB" ENABLES THE USER TO OBTAIN MARGINAL FREQUEN-
C	CIES FOR ANY ONE VARIABLE OR TO CROSS-TABULATE ANY PAIR OF VARI-
C	ABLES, USING A THIRD VARIABLE AS A CONTROL IF DESIRED.  THE
C	CONTROL VARIABLE MAY BE RESTRICTED TO ONE CATEGORY BY FOLLOWING
C	THE THIRD VARIABLE NUMBER WITH AN EQUALS SIGN (=) AND A CATEGORY
C	NUMBER (0 TO 9).  FOLLOWING THE THIRD VARIABLE NUMBER WITH AN
C	INEQUALITY SIGN (<>) AND A CATEGORY NUMBER HAS THE EFFECT OF
C	EXCLUDING RESPONDENTS IN THAT CATEGORY.  IF TWO OR THREE VARI-
C	ABLES ARE SPECIFIED, ONE OR MORE OUTPUT OPTIONS MUST BE SELECTED
C	AND THE APPROPRIATE CODE NUMBERS ENTERED.  THE FOLLOWING OPTIONS
C	ARE AVAILABLE:
C		0--EXCLUSION ANALYSIS ONLY
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 "ITEM" PRODUCES A MATRIX OF ITEM INTERCORRELATIONS
C	(GOODMAN AND KRUSKAL'S GAMMA) FOR AS MANY AS NINE VARIABLES.  A
C	VARIABLE PRECEDED BY A MINUS SIGN HAS ITS CATEGORIES REVERSED.
C	WHEN THE COMMAND IS GIVEN AS "ITEM PART", A CONTROL VARIABLE MAY
C	BE SPECIFIED.  CORRELATIONS MAY BE LIMITED TO A CERTAIN SET OF
C	RESPONDENTS BY FOLLOWING THE CONTROL VARIABLE WITH AN EQUALITY
C	OR INEQUALITY SIGN AND A CATEGORY NUMBER.
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.
