Dear all,
I'm trying to estimate some parameters with the optim() function but I
need to restrict one parameter and I have not found how to do it.
Could you help me please?
my program is basically
fn<-function(s)
initial<-function(r)
{
cst<-r[1]
cst1<-r[2]
beta<-r[3]
rho<-r[4]
p1<-r[5]
return(-sum())
}
parms<-c()
m0<-optim()
I need to specify 0<=p1<=1.
Thank you very much
