Likelihood ratio test

Description

Likelihood ratio test

Usage

LR_test(
  modelProteinF,
  modelName,
  modelProteinF_Int,
  modelName_Int,
  subject_Id = "protein_Id",
  path = NULL
)

Arguments

modelProteinF	table with models (see build model)
modelName	name of model
modelProteinF_Int	reduced model
modelName_Int	name of reduced model
subject_Id	subject id typically Assession or protein_Id
path	default NULL, set to a directory if you need to write diagnostic plots.
