RESCALED SUMName:
with N denoting the number of observations. This statistic has application in the ISO 13528 proficiency testing standard.
where <y> is the response variable; <par> is a parameter where the computed rescaled sum is saved; and where the <SUBSET/EXCEPT/FOR qualification> is optional.
<SUBSET/EXCEPT/FOR qualification> where <y1> is the first response variable; <y2> is the second response variable; <par> is a parameter where the computed difference of the rescaled sums is saved; and where the <SUBSET/EXCEPT/FOR qualification> is optional. This syntax computes the recaled sum of <y1> and <y2> and then computes the difference of the two sums.
LET A = RESCALED SUM Y1 SUBSET TAG > 2 LET A = DIFFERENCE OF RESCALED SUM Y1 Y2
To specify this value, enter the command
where <value> is typically 3 or 4 (if the reponse data are zscores or zscore type data). Note that the value represents an absolute value. For example, if CAPVALUE is 4, values greater than 4 will be set to 4 and values less than 4 will be set to 4.
