resids

VALIDATE Validate fractional model time-domain identification results

 Usage:  [ERR, STATS] = RESIDS(ID, G|FSIM, OPTS)

         where ERR is the optional output argument which contains the
                   absolute error vector y(t) - y_id(t) at time points
                   specified in ID.
               STATS is a structure with the following entries:
                     .MaxError -- maximum absolute value of the simulation
                                  error,
                     .Mean -- mean value of residuals,
                     .ResidNorm -- residual norm: sum(err^2)
                     .MSE -- mean squared error: 1/N sum(err^2)
                     .RErr -- vector with autocorrelation values of
                              residuals for lags tau up until tau_max

               If output arguments are omitted, plots validation results

         Inputs:
               ID is a FIDATA structure with validation data,
               G is the model to generate statistics for, or a FSPARAM
               structure if residual analysis is done on the basis of
               approximation,
               OPTS is a structure with the following entries (optional)
                    .Conf -- measure of confidence in (0.0, 1.0]. Defaults
                             to 0.95 (i.e., 95% confidence),
                    .MaxTau -- maximum number of lags to consider for the
                               autocorrelation of residuals test, defaults
                               to 50
