Thrilled to share that **fect** has won the 2025 Best Statistical Software Award from the Society of Political Methodology. We're honored! polmeth.org/statistical-... To celebrate, we've just released fect v2.0.5 on CRAN & Github 🎉

Honored by this recognition!

Glad this paper is finally out in @apsrjournal.bsky.social, five years after we began the project. Hope it proves useful to researchers. www.cambridge.org/core/journal... Software support: yiqingxu.org/packages/fec...
