%description
Prediction is one of the most important activities while working with time
series. There are many alternative ways to model the time series. Finding
the right one is challenging to model them. Most data-driven models
(either statistical or machine learning) demand tuning. Setting them right
is mandatory for good predictions. It is even more complex since time
series prediction also demands choosing a data pre-processing that
complies with the chosen model. Many time series frameworks have features
to build and tune models. The package differs as it provides a framework
that seamlessly integrates tuning data pre-processing activities with the
building of models. The package provides functions for defining and
conducting time series prediction, including data pre(post)processing,
decomposition, tuning, modeling, prediction, and accuracy assessment. More
information is available at Izau et al. <doi:10.5753/sbbd.2022.224330>.
