questions about optim
Hi,
I am trying to do parameter estimation with optim, but I can't get it to
work quite right-- I have an equation X = Y where X is a gaussian, Y is a
multinomial distribution, and I am trying to estimate the probabilities of
Y( the mean and sd of X are known ), Theta1, Theta2, Theta3, and Theta4; I
do not know how I can specify the constraint that Theta1 + Theta2 + Theta3 +
Theta4 = 1 in
