%description
Latent group structures are a common challenge in panel data analysis.
Disregarding group-level heterogeneity can introduce bias. Conversely,
estimating individual coefficients for each cross-sectional unit is
inefficient and may lead to high uncertainty. This package addresses the
issue of unobservable group structures by implementing the pairwise
adaptive group fused Lasso (PAGFL) by Mehrabani (2023)
<doi:10.1016/j.jeconom.2022.12.002>. PAGFL identifies latent group
structures and group-specific coefficients in a single step. On top of
that, we extend the PAGFL to time-varying coefficient functions.
