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? See also
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 Window:
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?
Version HistoryIntroduced before R2006a
R2022b: Time-domain estimation data is accepted in the form of timetables and matrices
Most estimation, validation, analysis, and utility functions now accept time-domain
input/output data in the form of a single timetable that contains both input and output data
or a pair of matrices that contain the input and output data separately. These functions
continue to accept
iddata objects as a data source as well, for
both time-domain and frequency-domain data.
