The requested delays in the model are too large compared to the size of the estimation data provided.

One or more data experiments contain too few data samples for model estimation.

There are too many parameters to estimate for chosen estimation data size. Reduce model order or use a larger data set.

When frequencies are defined by a range, use a cell array of two elements: FREQ = '{'Wmin, Wmax'}'.

For time series data, the orders should be provided as [na nc]. Type "help armax" for more information on orders.

The "rpem" command requires data with inputs. For time series data, use the "rarmax" or "rarx" command instead.
