Summing functions of lists
Hi
I'm trying to sum functions of lists with different lengths. Here is a simplified example of the problem:
r=list(1:3,1:5,1:2)
r
[[1]]
[1] 1 2 3
[[2]]
[1] 1 2 3 4 5
[[3]]
[1] 1 2
x=function(i,j) sum(j*r[[i]]) # x is a function of two parameters: i & j
y=function(j) # y is the sum of x over i

Error in nlm : non-finite value supplied by 'nlm'
Hello,
I am trying to compute MLE for non-Gaussian AR(1). The error term follows a difference poisson distribution. This distribution has one parameter (vector[2]).
So in total I want to estimate two parameters: the AR(1) paramter (vector[1]) and the distribution parameter.
My function is the negative loglikelihood derived from a mixing operator.
f=function(vector)
