Continue iter. This action continues parameter estimation using the most
recent model.
How to Refine Linear Parametric Models a t the
Command Line
If you are working at the comm and line, yo u can use pem to refine parametric
model estimates.
The general syntax for refining initial models is as follows:
m = pem(data,init_model)
pem
uses the properties o f the initial model unle ss you specify different
properties. F or more information about specifying model properties directly in
the estimator, see “Specifying Model Properties fo r Estimation” on page 2-16.
