...did not help me, because they advised a solution, when function was the same, but limits of the integral were vectors. I have got everything other way around. I could not get any result. I would be very grateful for an advice on this matter. The code is below. The function needed to be integrated (undint with respect to u from 0 to Inf). Sincerely, V. Code rm=list(ls()) #index matrix t1<-c(1:15) t2<-c(1:5)%x%matrix(1,3,1) t3<-matrix(1,3,1)%x%c(1:5) t4<-c(1:3)%x%matrix(1,5,1) comb<-cbind(t1,t2,t3,t4) nu<-rchisq(15,4) gam<-matrix(rchisq(75,df=5),15,5) undint<-function(u...
