    Whenever you change data in the variantlist in sheet1, the table withautomatically update (or if your automatic calculation is deactivated,which is done in the tools menu under options, press shift+F9 toupdate activated sheet). Note that this applies only to variantdata that is changed (not if you enter the name and data of a newmanuscript, then you must perform the analysis afresh).

    Additional options and featuresYou can now experiment with the same example in which you can choosein the quantitative analysis to exclude some of the variants (rememberthat variant 1 is in row2, etc). This is useful if you want to excludea variant for some or other reason. You may also choose to have theoutput data in fractions (not percent). Then you will be able to seehow many variants the statistic comparison is based upon. This isuseful to be able to evaluate the statistical significance, i.e. ifa manuscript has a lot of lacuna it will not be evident from thefigures given in percent. Another option is to choose only a part ofthe total number of witnesses (or variants). The software willautomatically include witnesses from left to the right, and variantsfrom the top to bottom (but remember that you have a special textboxin which you may exlude whatever variants).

    Non-majority analysisWith this feature you may enter the textual data of the Majority Text.This must be done in the last column (to the right).

    TR MS1 MS2 MS3 MS4 MS5 MT (Majority-Text in the last1 0 1 2 2 2 1 column)1 2 1 2 3 3 21 1 1 1 1 0 11 2 2 1 0 2 11 1 1 2 2 1 1

    Then you choose the QAnalys and Quantitative analysis submenu. Thedialogue box will appear again and this time you check the box"Non-Majority count". Be sure not to include the Majority-Text inthe "Numbers of witnesses" (in this example write 5 again). In the

    non-Majority analysis it is very useful to get output in fractions,especially when you work with Byzantine witnesses since these willcompared in few or any variants (and thus it is important to see ifthe statistics is significant enough, i.e. based on enoughcomparisons). In this example (of course with a far too smallsample) we choose to place our output data on sheet3 where thefollowing table will be generated:

    TR MS1 MS2 MS3 MS4 MS5TR 0/0 1/1 0/0 0/1 0/1MS1 0/0 1/1 0/0 0/0 1/1MS2 1/1 1/1 0/0 0/1 1/2MS3 0/0 0/0 0/0 2/2 1/1

    Comparisons in tablesThis function allows the user to generate the data into a morereadable format, namely a table for each MS with the other MSScompared in descending order. The function "Comparisons in tables"is available in the toolsmenu under QAnalys, below the Quantitative

    analysis. This function will only work when you have generated atleast one table where the output is given in percent (fractionscannot be arranged in this way). You may include the sheet whereyou have performed your non-Majority analysis and this data may bein fractions and will be brought into the corresponding placeaccording to the percentage data. In our example we first redo theordinary quantitative analysis and include the MT as a witness andchoose sheet2 as outputsheet. Then we choose the "Comparisons intables"-function in which we enter the total number of witnesses(including the MT), then below we write "sheet2" (worksheet withinput data) and we choose to include the generated non-Majoritycomparisons that we have in fractions on sheet3. For output we write"sheet4". The following table will appear on sheet4:

    TR MS1 MS2 MS3 MS4MS2 80 1/1 MS2 75 1/1 TR 80 1/1 MS4 75 2/2 MS3 75 2/2MT 80 MT 75 MS1 75 1/1 MT 60 MS5 66 2/2MS1 50 0/0 MS5 66 1/1 MT 60 MS1 50 0/0 MS1 33 0/0MS3 40 0/0 TR 50 0/0 MS5 50 1/2 TR 40 0/0 TR 25 0/1MS4 25 0/1 MS3 50 0/0 MS4 25 0/1 MS5 25 1/1 MS2 25 0/1MS5 25 0/1 MS4 33 0/0 MS3 20 0/0 MS2 20 0/0 MT 25

    MS5 MTMS1 66 1/1 TR 80MS4 66 2/2 MS1 75MS2 50 1/2 MS2 60TR 25 0/1 MS3 60MS3 25 1/1 MS4 25MT 25 MS5 25

    In this table you can see that MS2 and the TR are 80% in totalagreement and MS3 and MS4 75% in total agreement. However MS3and MS4 share two non-Majority variants. As is apparent fromthe MS5 table the software will arrange according to percent buthere we have the same percentage for MS1 and MS4 (66%) and ideallythen it should arrange according to next column so that MS4 isdisplayed on the top because it has 2/2 non-Majority agreement. Thisis something for the future development of this software and in factthe source code is available to anyone interested. (Send the designer

    an e-mail: [email protected]).

    Error messagesIf you get an error message you have probably entered an unexpectedvariable in a dialouge box (e.g. "4" instead of "sheet4", etc). Ifyou have questions send a note to the above e-mailadress. I cannotnot promise to answer, but keep on knocking on the door :-)
