I’m having difficult knowing what questions I need to ask the author to resolve the following formula which appears as follows . There are curly braces around the second sigma group, but I do not see that as having any mathematical significance. XYi is a value obtained from a table which I don’t have at moment. I’m assuming that the “i” is the same as the index in the first Summation. The uppercase N in the second part is currently undefined unless there is some convention that assigns it a value. KPO and Z in the second part are defined and I believe the “i” and the “n” in the second part both relate to the indices so that in the first iteration, they would both equal 1.
Can someone confirm that I need to ask for the value of “N” and can anyone rewrite the formula in simple algebraic format so that I can express AB in an Excel cell?
