%description
Large panel data sets are often subject to common trends. However, it can
be difficult to determine the exact number of these common factors and
analyse their properties. The package implements the Barigozzi and Trapani
(2022) <doi:10.1080/07350015.2021.1901719> test, which not only provides
an efficient way of estimating the number of common factors in large
nonstationary panel data sets, but also gives further insights on factor
classes. The routine identifies the existence of (i) a factor subject to a
linear trend, (ii) the number of zero-mean I(1) and (iii) zero-mean I(0)
factors. Furthermore, the package includes the Integrated Panel Criteria
by Bai (2004) <doi:10.1016/j.jeconom.2003.10.022> that provide a
complementary measure for the number of factors.
