Initial CRAN release.
Implements three estimation methods for time-invariant variables in panel FE models:
fevd(): Fixed Effects Vector Decomposition (Plümper & Troeger, 2007)fef(): Fixed Effects Filtered (Pesaran & Zhou, 2018)fef_iv(): FEF with instrumental variables (Pesaran & Zhou, 2018)Uses correct Pesaran-Zhou (2018) variance estimators that account for generated regressor uncertainty.
Provides bw_ratio() diagnostic for between/within variance analysis.
Full S3 methods: print(), summary(), coef(), vcov(), confint().
