Changes in version 0.2.4.900 - Correction of small error when cluster or fixed were NULL. Changes in version 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. Changes in version 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. Changes in version 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. Changes in version 0.2.0.900 - bootstrap function added - gamma_val option added for plugin Lasso - Two possible collinearity checks introduced Changes in version 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. Changes in version 0.1.0.900 - Added a NEWS.md file to track changes to the package.
