endog : arraylike, pandas.Series
The series to model. It is best to use a pandas object with a
DatetimeIndex or PeriodIndex. However, you can pass an arraylike
object. If your object does not have a dates index then start and
freq are not optional.
maxorder : tuple
The maximum order of the regular and seasonal ARMA polynomials to
examine during the model identification. The order for the regular
polynomial must be greater than zero and no larger than 4. The
order for the seaonal polynomial may be 1 or 2.
maxdiff : tuple
The maximum orders for regular and seasonal differencing in the
automatic differencing procedure. Acceptable inputs for regular
differencing are 1 and 2. The maximum order for seasonal differencing
is 1. If diff is specified then maxdiff should be None.
Otherwise, diff will be ignored. See also diff.
diff : tuple
Fixes the orders of differencing for the regular and seasonal
differencing. Regular differencing may be 0, 1, or 2. Seasonal
differencing may be 0 or 1. maxdiff must be None, otherwise
diff is ignored.
exog : arraylike
log : bool or None
If None, it is automatically determined whether to log the series or
not. If False, logs are not taken. If True, logs are taken.
outlier : bool
Whether or not outliers are tested for and corrected, if detected.
trading : bool
Whether or not trading day effects are tested for.
forecast_years : int
Number of forecasts produced. The default is one year.
retspec : bool
Whether to return the created specification file. Can be useful for
debugging.
speconly : bool
Whether to create the specification file and then return it without
performing the analysis. Can be useful for debugging.
start : str, datetime
Must be given if endog does not have date information in its index.
Anything accepted by pandas.DatetimeIndex for the start value.
freq : str
Must be givein if endog does not have date information in its
index. Anything accapted by pandas.DatetimeIndex for the freq value.
print_stdout : bool
The stdout from X12/X13 is suppressed. To print it out, set this
to True. Default is False.
x12path : str or None
The path to x12 or x13 binary. If None, the program will attempt
to find x13as or x12a on the PATH or by looking at X13PATH or
X12PATH depending on the value of prefer_x13.
prefer_x13 : bool
If True, will look for x13as first and will fallback to the X13PATH
environmental variable. If False, will look for x12a first and will
fallback to the X12PATH environmental variable. If x12path points
to the path for the X12/X13 binary, it does nothing.
