outer function problems
I'm pulling my hair (and there's not much left!) on this one. Basically I'm not getting the same result t when I "step" through the program and evaluate each element separately than when I use the outer() function in the FindLikelihood() function below. Here's the functions: Dk<- function(xk,A,B) { n0 *(A*exp(-0.5*(xk/w)^2) + B) } FindLikelihood <- function(Nk) { A <- seq(0.2,3,by=0.2) B <- seq(0.2,3,by=0.2) k <-7 L <- outer(A, B, function(A,B) sum( (Nk*log(Dk(seq(-k,k),A,B))) - Dk(seq(-...
