I am trying to optimize a nested function using nlminb. This throws out an error that y is missing. Can someone help me with the correct syntax?? Thank you.
See ?nlminb. The parameters to optimize should be given as a vector in a single parameter. Other parameters are kept fixed through the optimization, and need to be passed in the nlminb call. Duncan Murdoch
test1<- function(x,y)
{
sum<- x + y
return(sum)
}
test2<- function(x,y)
{
sum<- test1(x,y)
sumSq<- sum*sum
return(sumSq)
}
nlminb(start = c(1,1), test2,lower = c(0,0), upper = c(5,5))
