Dear R-users,
I would like to maximize the function g above which depends on 4 parameters (2
vectors, 1 real number, and 1 matrix) using optim() and BFGS method. Here is
my code:
# fonction to maximize
g=function(x)
{
x1 = x[1:ncol(X)]
x2 = x[(ncol(X)+1)]
x3 =
matrix(x[(ncol(X)+2):(ncol(

Dear R-users,
I would like to use optim( ) to minimize a function which depends on 4
parameters: 2 vectors, a scalar, and a matrix.
And I have a hard to define the parameters at the beginning of the function,
and then to call optim. Indeed, all the examples I have seen dont treat cases
