Then, I use the fonction optim for obtaining a vector of 7 parameters which
will minimise the fonction sce. I use initial parameters at random that I
don't have a answer relating to a minimum local.
pinit=c(runif(3,min=0,max=10), runif(3,min=3,max=8),runif(1,min=0,max=4))
optim(p=pinit,sce)
if I use the function as above, I got an answer but the value of the
parameters is not in the interval I want. So I applied
optim(p=pinit,sce, method="L-BFGS-B", lower=c(0,0,0,0,0,0,0), upper=c(10,
