[R] Why different results with different initial values for MLE (optim)!

2006-06-22 Thread Xin
Hi, All: I used optim() to minimise likelihood function for fitting the data to a partiuclar distribution. The function is converged and the value of log-likelihood is different when I change the intial value. Whether it means the program does not work well? Thanks! Xin
