Hi everybody,
I am using the L-BFGS-B method of the mle2() function to estimate the values
of 6 parameters. mle2 uses the methods implemented in optim. As I got it
from the descriptions available online, one can use the parscale
parameter to tell R somehow what the values of the estimated parameters
should be . . .
Could somebody please help me understand what one has to do actually with
the parscale parameter so that it works right?
I am very grateful for an answer - R leaves sometimes some of the parameters
unchanged (it is OK since it is a feature of the L-BFGS-B algorithm), but
often these are the parameters that should have greater values!
Thank you in advance!
Zoe
