Analysis and recommendations for data or estimated linear models
advice(data) displays the following information
about the data in the MATLAB® Command Window:
What are the excitation levels of the signals and
how does this affect the model orders? See also
Does it make sense to remove constant offsets and
linear trends from the data? See also
Is there an indication of output feedback in the data?
Would a nonlinear ARX model perform better than a linear ARX model?
advice(model,data) displays the following
information about the estimated linear model in the MATLAB Command
Does the model capture essential dynamics of the system and the disturbance characteristics?
Is the model order higher than necessary?
Is there potential output feedback in the validation data?
