- MarkovAutoregression.predict(params, start=None, end=None, probabilities=None, conditional=False)¶
In-sample prediction and out-of-sample forecasting
- Parameters:
- params
ndarray
Parameters at which to form predictions
- start
int
,str
,or
datetime
,optional
Zero-indexed observation number at which to start forecasting, i.e., the first forecast is start. Can also be a date string to parse or a datetime type. Default is the the zeroth observation.
- end
int
,str
,or
datetime
,optional
Zero-indexed observation number at which to end forecasting, i.e., the last forecast is end. Can also be a date string to parse or a datetime type. However, if the dates index does not have a fixed frequency, end must be an integer index if you want out of sample prediction. Default is the last observation in the sample.
- probabilities
str
or array_like,optional
Specifies the weighting probabilities used in constructing the prediction as a weighted average. If a string, can be ‘predicted’, ‘filtered’, or ‘smoothed’. Otherwise can be an array of probabilities to use. Default is smoothed.
- conditionalbool or
int
,optional
Whether or not to return predictions conditional on current or past regimes. If False, returns a single vector of weighted predictions. If True or 1, returns predictions conditional on the current regime. For larger integers, returns predictions conditional on the current regime and some number of past regimes.
- params
- Returns:
- predict
ndarray
Array of out of in-sample predictions and / or out-of-sample forecasts.
