3 Linear Model Identification
Parameter table displays Auto . If you do not have a good guess for the
parameter values,
Auto works better than entering an ad hoc value.
5 (Optional) If you approximately know a parameter value, enter this value
in the Initial Guess column of the Parameter table. The estim ation
algorithm uses this value as a starting point. If you know a parameter
value exactly, enter this value in the Initial Guess column, and also se lect
the corresponding Known check box in the table to fixitsvalue.
If you kn
ow the rang e of possible values for a parameter, enter these values
into the
corresponding Bounds field to help the estim ation algorithm.
