%description
Provides tools for fitting periodic coefficients regression models to data
where periodicity plays a crucial role. It allows users to model and
analyze relationships between variables that exhibit cyclical or seasonal
patterns, offering functions for estimating parameters and testing the
periodicity of coefficients in linear regression models. For simple
periodic coefficient regression model see Regui et al. (2024)
<doi:10.1080/03610918.2024.2314662>.
