- glmhdfe — with Joschka Wanner, and Alexander Hudlet

The R package glmhdfe implements a fast estimation procedure of generalized linear models with high dimensional fixed effects. The package makes use of a convenient property of

*some*combinations of error term distributions and link functions, where the fixed effects have — conditional on all other estimated parameters — an explicit solution.Install from Github via the remotes package:

`install.packages("remotes") remotes::install_github("julianhinz/R_glmhdfe")`

A Stata implementation is coming soon. For more details and usage examples check out the R_glmhdfe Github repository and the technical note.

- gravity.distances

The R package gravity.distances provides distances between geographic entities — such as countries, US states or Canadian provinces — that are consistent with the gravity equation in international economics.

To install the package in R, simply run the following commands:

`install.packages("remotes") remotes::install_github("julianhinz/gravity.distances")`

For more details and usage examples check out the respective Github repositories:

- R package: gravity.distances
- Dataset repository: gravity.distances_data
