In tomzylkin/penppml: Penalized Poisson Pseudo Maximum Likelihood Regression

penppml 0.2.4.900

• Correction of small error when cluster or fixed were NULL.

penppml 0.2.3.900

• Correction of small error that was appearing in the CRAN checks.
• colcheck option added, allowing to simultaneously check whether the independent variables are
• collinear or are perfectly explained by the fixed effects.

penppml 0.2.2.900

• phipost option added for plugin Lasso, allowing the coefficient-specific penalty weights
• to be iteratively calculated using estimates from a post-penalty regression.

penppml 0.2.1.900

• When post = FALSE, there was a mistake in the last version where a non-existent
• vector of coefficients was being stored. This issue is now corrected.

penppml 0.2.0.900

• bootstrap function added
• gamma_val option added for plugin Lasso
• Two possible collinearity checks introduced

penppml 0.1.1.900

• When standardize option = TRUE and selected penalty is ridge, there was a mistake in last
• version when rescaling the coefficients. The rescaling is now performed correctly.
• collapse::fhdwithin has replaced lfe::demeanlist in internal hdfeppml_int()-function.
• This has no practical implications for users.

penppml 0.1.0.900

• Added a NEWS.md file to track changes to the package.
