Use to specify starting estimates for the shape and the maximum number of iterations when available.
Use starting estimate for shape: Enter starting estimates for the shape. You can provide as many starting estimates as there are response columns. If you provide fewer starting estimates than there are response columns, the last shape value listed is used for the remaining variables.
Maximum number of iterations: Enter a positive integer to specify the number of iterations. The default number of iterations is 20.
