train.tspred: Train method for 'tspred' objects

In TSPred: Functions for Benchmarking Time Series Prediction

Train method for tspred objects

Description

Fits a model to the time series data contained in a tspred class object based on a particular model training method. The model training method is defined by a modeling object contained in the tspred class object.

Usage

## S3 method for class 'tspred'
train(obj, ...)

Arguments

obj	An object of class tspred defining a particular time series prediction process.
...	Ignored

Details

The function train.tspred calls the method train on the modeling object for each time series contained in obj. Finally, the produced time series model is introduced in the structure of the tspred class object in obj.

If any modeling parameters are computed during training, they are duly updated in the structure of the tspred class object in obj. This is important for provenance and reprodutibility of the training process.

Value

An object of class tspred with updated structure containing the produced trained time series models.
