plot_lasso_paths

This function displays coefficient trajectories from LASSO-regularized DIF detection.

Methods to detect differential item functioning (DIF) in dichotomous, polytomous,
and continuous items, using both classical and modern approaches. These include
Mantel-Haenszel procedures, logistic regression (including ordinal models), and
regularization-based methods such as LASSO. Uniform and non-uniform DIF effects
can be detected, and some methods support multiple focal groups. The package
also provides tools for anchor purification, rest score matching, effect size
estimation, and DIF simulation. See Magis, Beland, Tuerlinckx, and De Boeck
(2010, Behavior Research Methods, 42, 847–862, <doi:10.3758/BRM.42.3.847>) for
a general overview.
