to R Core T: mle function in 32bits not respecting the constrain
...thod =
"L-BFGS-B",lower=llim*reduction)*
lower = -0.01570427
The optimizer (optim function in 32 bits) display:
-0.015704 -loglik 48.690236
-0.015704 -loglik 48.690236
-0.017704 -loglik 1.#QNAN0
And it is not respecting the lower constrain.
Could anyone explain me why this? Maybe I am misunderstunding of lower
parameter meaning.
Is this because the 'lower' is for the estimate but not for the hessian
calculations internally? In such a case, why in 64 bits is different from
32 bits?
And how I could solve it?
Thank you.
