hessian fails for box-constrained problems when close to boundary?
...x though, simple param
transformations do not apply ashere), imagine estimating mu and sigma
(restricted to be >0) of a simple normally distributed data, where however
the true sigma is very close to zero:
LLNorm <- function(para, dat=rn) return(-sum(dnorm(dat, para[1], para[2],
log=TRUE)))
rn2 <- c(rep(10.3, 2000), 10.31)
>optim(c(10,1), fn=LLNorm, method="L-BFGS-B", lower=c(-Inf, 0.0000001),
dat=rn2,hessian=TRUE)
Error in optim(c(10, 1), fn = LLNorm, method = "L-BFGS-B", lower = c(-Inf,
: non-finite finite-difference value [2]

Reconstruct a dataset
...ke this:
inividual var1 var2 ?
1 1 1 ?
2 1 2 ?
3 2 1 ?
4 2 2 ?
? ? ? ?
I will random sample 2 individuals from this dataset based on a set of
random numbers, e.g.,
rn1 <- c(0, 0, 1, 1), rn2 <- c(0, 0, 2, 0), rn3 <- c(1, 0, 0, 1), rn4 <-
c(0, 1, 1, 0),?
After reconstructed the samples, I have a dataset that looks like this:
id var1.1 var1.2 var2.1 var2.2 ?
1 2 2 1 2 ?
2 2 2 1 1 ?
3 1 2 1 2 ?...
