I have the following function; f(x)=n*log(a)+(b-1)*sum(log x(i))+sum(b+c*x(i))+n*log(1-d)-sum(a*x(i)^b*exp(c*x(i)))+sum(c*x(i))-2*sum(log(1-d*exp(-a*x(i)^b*exp(c*x(i))))); i=1(1)5,0 0 and x(i)=[6 12 18 24 30]. How do I optimize this function with respect to a,b,c and d. Thank you for your assistance.

I have the following function;

f(x)=n*log(a)+(b-1)*sum(log x(i))+sum(b+c*x(i))+n*log(1-d)-sum(a*x(i)^b*exp(c*x(i)))+sum(c*x(i))-2*sum(log(1-d*exp(-a*x(i)^b*exp(c*x(i)))));

i=1(1)5,0<d<1;a,b,c>0 and x(i)=[6 12 18 24 30].

How do I optimize this function with respect to a,b,c and d. Thank you for your assistance.
