.INDENT 5
THE PEARSON R CORRELATION, MEAN AND STANDARD DEVIATION PROGRAM IS PART
OF THE WMU BANK SYSTEM. IT WAS DESIGNED FOR USERS WITH ONLY A LIMITED
KNOWLEDGE OF THE PDP-10 SYSTEM TO ANALYZE THEIR OWN DATA. THE PROGRAM
IS INTERACTIVE, PROMPTING USERS FOR NEEDED INFORMATION. THE USER MAY
REQUEST ADDITIONAL INFORMATION BEFORE RESPONDING TO ANY QUERY BY SIMPLY
TYPING "HELP".
.SKIP 1
.INDENT 5
THE CORL PROGRAM CAN PROCESS LARGE DATA SETS FROM A TERMINAL, DISK,
MAGNETIC TAPE, DECTAPE OR A STRUCTURED DATA BANK. OUTPUT CAN BE
DIRECTED TO DISK, TERMINAL, LINEPRINTER, MAGNETIC TAPE OR DECTAPE.
OPTIONS ARE AVAILABLE TO TREAT MISSING DATA EITHER PAIR-WISE OR
OBSERVATION-WISE; TO CALCULATE T-VALUE AND Z-VALUE STATISTICS;
TO ENTER A USER SPECIFIED FORMAT; AND TO SUBSET THE DATA BY ELIMINATING
THOSE OBSERVATIONS NOT MEETING USER SPECIFIED CRITERIA. VARIABLES MAY
EITHER BE F OR I-TYPE AND CAN BE REFERRED TO BY EITHER VARIABLE NUMBERS
OR VARIABLE NAMES (IF DEFINED).
.SKIP 1
.INDENT 5
FOR EACH DATA SET, THE PROGRAM CALCULATES THE MEAN, VARIANCE, STANDARD
DEVIATION AND CORRELATION MATRIX FOR ALL THE VARIABLES ELECTED. A TABLE
OF SAMPLE SIZES IS GIVEN IF THE MISSING DATA IS TREATED PAIR-WISE. DATA
DEFINED AS MISSING IN A BANK FILE WILL BE TREATED AS A MISSING DATA
SYMBOL IN CORL, AN OPTION ALSO EXISTS TO HAVE OTHER SYMBOLS BE DEFINED
AS MISSING DATA.

NOTE:##THE FORMAT CAN CONSIST OF UP TO 400 CHARACTERS,

SELECT THE SELECT OPTION ALLOWS THE USER TO SUBSET DATA BY CONSIDERING
ONLY THOSE OBSERVATIONS MEETING USER SPECIFIED CRITERIA. INSTRUCTIONS
INDICATING HOW SUBSETTING IS TO PROCEED ARE CALLED QUALIFIERS AND ARE
ENTERED ON ONE OR MORE LINES.
.SKIP 1
EACH QUALIFIER CONTAINS THREE BASIC PARTS: THE VARIABLE, THE CONDITION,
AND THE VALUE OR VALUES TO BE COMPARED AGAINST. THE VARIABLE MAY BE
SPECIFIED BY EITHER VARIABLE NAME (IF PREVIOUSLY DEFINED), OR THE
VARIABLE NUMBER (IN THE CASE OF DATA FILE, THIS IS THE NUMBER ASSOCIATED
WITH THE BANK VARIABLES). THE FOLLOWING CONDITIONS ARE AVAILABLE:

<= OR =< LESS THAN OR EQUAL TO

.SKIP 2
.FILL
THE VALUE TO BE COMPARED AGAINST MUST BE OF THE SAME TYPE AS THE
VARIABLE IT IS BEING COMPARED WITH. IN THE CASE OF A-TYPE VARIABLES
FROM THE DATA BANK, QUALIFIERS SHOULD HAVE THE VALUES ENCLOSED IN SINGLE
QUOTES. NO A-TYPE VARIABLES ARE PERMITTED IN NON-DATA BANK FILES.
.SKIP 1
EACH LINE OF QUALIFIERS ENTERED REPRESENTS A CONDITION WHICH MUST BE
SATISFIED BEFORE AN OBSERVATION WILL BE USED IN THE ANALYSIS. THAT IS,
EACH LINE OF QUALIFIERS WILL BE "ANDED" WITH ALL OTHER LINES. ENTER
EACH "AND" QUALIFIER IMMEDIATELY AFTER THE "?" TYPED OUT BY THE PROGRAM.
FOR EXAMPLE: TO CONSIDER ALL THOSE OBSERVATIONS IN WHICH VARIABLE 3 IS
NOT ZERO AND THE SUBJECT IS A MALE.

EACH LINE OF QUALIFIERS MAY CONTAIN ONE OR MORE QUALIFIERS SEPARATED BY
SEMI-COLONS (;). AN OBSERVATION IS ACCEPTABLE TO A LINE OF QUALIFIERS
IF IT SATISFIES ONE OF THE QUALIFIERS LISTED ON THAT LINE. WHEN MORE
THAN ONE QUALIFIER IS LISTED ON A LINE, THE QUALIFIERS ARE "ORED" WITH
ALL OTHER QUALIFIERS ON THAT LINE. ENTER ALL THE QUALIFIERS TO BE "ORED"
TOGETHER ON ONE LINE IMMEDIATELY AFTER THE "?" TYPED OUT BY THE PROGRAM.
SEMI-COLONS (;) MUST BE USED TO SEPARATE THE QUALIFIERS. FOR EXAMPLE,
TO CONSIDER ALL THOSE OBSERVATIONS IN WHICH VARIABLE 1 IS LESS THAN 9 OR
VARIABLE 4 IS EQUAL TO 2.

AN EXTRA FEATURE IS AVAILABLE IN THE CASE WHERE THE CONDITION CHOSEN IS
AN "=". AS MANY AS 20 VALUES MAY BE ENTERED, SEPARATED BY COMMAS, AND
THE RELATIONSHIP WILL BE THAT OF "OR". FOR INSTANCE, THE QUALIFIER:
?3=1,2,3## MEANS AN OBSERVATION MUST HAVE VARIABLE NUMBER 3 EQUAL TO
THE VALUE 1, OR THE VALUE 2, OR THE VALUE 3 TO BE ACCEPTABLE.
.SKIP 1
WHEN THE LAST QUALIFIERS HAS BEEN ENTERED, A _^Z (CONTROL Z), CARRIAGE
RETURN (<CR>) OR A BLANK LINE SHOULD BE ENTERED IN RESPONSE TO THE
QUESTION MARK. FOR AN OBSERVATION TO BE USED AS DATA, IT MUST SATISFY
EACH LINE OF QUALIFIERS ENTERED.
.SKIP 1
EXAMPLE: TO CONSIDER ALL THOSE OBSERVATIONS IN WHICH VARIABLE 1 IS NOT
ZERO; AND THE SUBJECT IS A MALE; AND VARIABLE 4 IS LESS THAN 8 OR
VARIABLE 3 IS EITHER 1, 2, OR 3. (NOTE: THERE ARE 4 QUALIFIERS

IN THE PAIR-WISE METHOD, SHOULD A VARIABLE HAVE A MISSING DATA SYMBOL IN
AN OBSERVATION, CALCULATION BETWEEN THAT VARIABLE AND ALL OTHER
VARIABLES ARE IGNORED FOR THAT PARTICULAR OBSERVATION, HOWEVER,
CALCULATION IS PERFORMED AMONG OTHER VARIABLES NOT CONTAINING MISSING
DATA. THE MISSP OPTION IS MANDATORY IF MISSING DATA IS TO BE TREATED
PAIRWISE. CAUTION SHOULD BE USED WHEN USING PAIRWISE DELETION FOR

.SKIP 2
SINCE ONLY ONE METHOD OF HANDLING MISSING DATA CAN BE USED AT ONE TIME
THE OPTIONS "MISSR","MISSM" AND "MISSP" CANNOT BE USED TOGETHER.
OPTIONS "TVALUE" AND "ZVALUE" WILL BE IGNORED IF OPTIONS "MISSR" OR
"MISSM" ARE USED SINCE THEY ARE NOT VALID.
