Estimation data. For time domain estimation, For frequency domain estimation,
For multiexperiment data, the sample times and intersample behavior of all the experiments must match. 

Output error model orders. For a system represented by: $$y(t)=\frac{B(q)}{F(q)}u(tnk)+e(t)$$ where y(t) is the output, u(t) is the input and e(t) is the error.
For estimation using continuoustime data, only specify

Specify optional commaseparated pairs of Name,Value
arguments.
Name
is the argument
name and Value
is the corresponding
value. Name

You can specify several name and value pair
arguments in any order as Name1,Value1,...,NameN,ValueN
.

Input delay for each input channel, specified as a scalar value
or numeric vector. For continuoustime systems, specify input delays
in the time unit stored in the For a system with You can also set Default: 0 

Transport delays. For continuoustime systems, specify transport delays in the
time unit stored in the For a MIMO system with Default: 

Identified OutputError polynomial model.

OutputError models are a special configuration of polynomial
models, having only two active polynomials  B and F.
For such models, it may be more convenient to use a transfer function
(idtf
) model and its estimation
command, tfest
.
Also, tfest
is the recommended
command for estimating continuoustime models.
