In Column Details , the value for Agreement Weight and Disagreement Weight are :
InputName Agreement Disagreement
ALEXANDER,3.3,-3.18
ALEX ,2.3,-3.03
ALEXENDER,3.3,-3.18
For BARTON , the agreement weight is 1.3

for the Match Command , the comparison types i use is NAME_UNCERT.
i try with different Param 1 values : 700 , 750 , 800 and 850.
The master record is ALEXANDER BARTON , the weight is 4.6 for all the time.
Param 1 Weight for ALEXENDER BARTON
700,2.39
750,1.66
800,0.19

    Hi,

    Please take a look at the online documentation for a description of the PARAM values: http://publib.boulder.ibm.com/infocenter/iisinfsv/v8r5/index.jsp?topic=%2Fcom.ibm.swg.im.iis.qs.ug.doc%2Ftopics%2Fr_NAME_UNCERT_comparison.html

    Regarding the master score, it is the score achieved when matching the record to itself.

    I hope this helps!

    The exact algorithm for this is IBM proprietary information.
