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

Description

Title Fitting cmlDIF with L1-penalty via lbfgs (opitmized with lambda_max)

Title Fitting cmlDIF with L1-penalty via lbfgs (opitmized with lambda_max)

Usage

cml_lasso_win_lbfgs_optimized(
  data,
  covariates,
  DIF_type = "all.interactions",
  nlambdas = 21,
  tolerance_df = 0,
  ...
)

cml_lasso_win_lbfgs_optimized(
  data,
  covariates,
  DIF_type = "all.interactions",
  nlambdas = 21,
  tolerance_df = 0,
  ...
)

Arguments

data	matrix of responses
covariates	Matrix of covariate values of all persons (n x ncovs)
DIF_type	can be "items", "variables", "all.interactions", "none"
nlambdas	number of lambda parameters evenly spread between 10^-5 and lambda_max, which is calculated automatically
tolerance_df	Value under which parameters are considered equal to zero for the calculation of degreees of freedom

Value

list of lbfgs-optimization results for each lambda, the picked model and its parameters, the computing time

list of lbfgs-optimization results for each lambda, the picked model and its parameters, the computing time
