1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
x |
time series realization |
phi |
phi values associated with the ARIMA model |
theta |
theta values associated with the ARIMA model |
d |
differencing 'd' associated with the ARIMA model |
s |
seasonality 's' of the ARIMA model |
linear |
(TRUE|FALSE) If using a Signal Plus Noise model, should a linear signal be used? |
freq |
If using a sinusoidal signal, what is the frequency of the signal? |
n.ahead |
last n.ahead data points in each batch will be used for prediction and ASE calculations |
batch_size |
Window Size used |
step_n.ahead |
Whether to step each batch by n.ahead values (Default = FALSE) |
verbose |
How much to print during the model building and other processes (Default = 0) |
... |
any additional arguments to be passed to the forecast functions (e.g. max.p for sigplusnoise model, lambda for ARUMA models) |
Named list 'ASEs' - ASE values 'time_test_start' - Time Index indicating start of test time corresponding to the ASE values 'time_test_end' - Time Index indicating end of test time corresponding to the ASE values 'batch_num' - Indicates the batch number for each ASE value 'f' - Forecasts for each batch 'll' - Lower Forecast Limit for each batch 'ul' - Upper Forecast Limit for each batch 'time.forecasts' - Time Corresponding to each forecast, upper and lower limit values
