logistf 1.26.0

• forward() and backward() now require the dataset as an argument.
• Using forward() and backward() to select among factor variables is no longer supported.

logistf 1.25.0

• Fixed memory bug with large data sets in flic() (#45).
• Added support for emmeans: emmeans::emmeans() now works with logistf objects (#51).

logistf 1.24.1

• Added a NEWS.md file to track changes to the package.
• Added terms() to extract terms objects from logistf, flic and flac objects (#32).
• logistf() now issues warnings in case of non-convergence.
• logistf() more carefully checks its response argument to ensure that they’re specified correctly.
• logistf() has gained one new control parameter, modcontrol, that controls additional parameters for fitting, e.g. degree of penalization in the fitting process. Default is logistf.mod.control().
• Fixed a bug in backward() when data is called data (#34) and when function is called with factors as covariates (#34).
• Updated predict() function for easier handling.
• logistf(), flic() and flac() are now compatible with termplot() because of the added prediction type terms in predict.logistf(), predict.flic() and predict.flac().
• Added a new fitting method: Iteratively reweighted least squares (IRLS).
• Added na.action option to logistf() and predict.logistf().
• Updated flic() and flac() to be called with interactions in formula.
