penalization: penalization term

In submission-user/cmlDIFlasso: DIF-detection with Lasso-methods in a cML-Framework

Description

Calculates the certain amount of penalization depeding on DIF-type, lambda and for restriction of intercepts added

Usage

penalization(
  deltas,
  beta_intercept,
  DIF_type = c("items", "variables", "all.interactions", "none"),
  restr_pen = FALSE,
  lambda = 0,
  lambda_restr = 0
)

Arguments

deltas	A (ncovars x nitems) matrix of DIF-parameters
beta_intercept	A vector of #items parameters
DIF_type	can be "items", "variables", "all.interactions", "none"
restr_pen	For additional penalization to ensure zero sum of intercepts
lambda	penalization parameter
lambda_restr	penalization parameter for restriction

Value

A numeric value for penalization of the Loglikelihood
