Method. Select the maximum likelihood or restricted maximum likelihood estimation.
Iterations:
 Maximum iterations. Specify a non-negative integer.
 Maximum step-halvings. At each iteration, the step size is reduced by a factor of 0.5
until the log-likelihood increases or maximum step-halving is reached. Specify a
positive integer.
 Print iteration history for every n step(s). Displays a table containing the log-
likelihood function value and parameter estimates at every n iterations beginning
with the 0
th
iteration (the initial estimates). If you choose to print the iteration
history, the last iteration is always printed regardless of the value of n.
