Using Time series toolbox I have generated a network model and it takes 4 delay input and gives 4 delay output. Confusion is, what 4 delay output values represent. Is they are 4 predicted values, if so then which one is more accurate. Please clear.
Consider the current output to exist at time t and the 4 input delays and 4 output feedback delays to correspond to previous sig...
