```100'  NAME--STAT16
110'
120'  DESCRIPTION--COMPUTES THE ANALYSIS OF VARIANCE TABLE FOR
130'  A SIMPLE GRAECO-LATIN SQUARE DESIGN.
140'
150'  SOURCE--UNKNOWN
160'
170'  INSTRUCTIONS--PLACE DATA IN LINE 1100 AND FOLLOWING.
180'  FIRST DATA IS N, THE NUMBER OF TREATMENTS.  THEN
190'  THE MATRIX GIVING THE LATIN TREATMENT ASSIGNMENTS
200'  (NUMBERED FROM 1 TO N ONLY) IS ENTERED. FOLLOWING
210'  THAT THE MATRIX GIVING THE GRAECO TREATMENTS IS ENTERED.
220'  FINALLY THE MATRIX OF DATA IS ENTERED. ALL MATRICES SHOULD
230'  BE ENTERED BY ROWS. IF N IS GREATER THAN 10 A DIM
240'  STATEMENT SHOULD BE ADDED TO THE PROGRAM.
250'  SAMPLE DATA ARE IN LINES 1100 THROUGH 1160.
