After reading numerous threads … WebThere are different ways of doing this in GAMS. You cannot directly. compare set elements with the relation operators. You could do the. following: 1) sum (y$ (y.uel ks.uel), 2) sum (y$ (y.pos ks.pos), 3) sum (y$ (not sameas (y,ks)), All three methods are described in the Bruce McCarl's Extended User's.
WebConditional summing (R) I'm trying to create a conditional sum, in order to calculate an average. The idea is that an function (or an apply statement) checks if an certain value is true (for example x > 0), then sums all the values of x that where higher than zero. The last step would be to divide this sum by the number of instances which are ... WebJan 20, 2012 · Teams. Q&A for work.
