You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: IAMB.m
    path of file: ./repos/MIToolbox/matlab/demonstration_algorithms
    
    the code of the file until where you have to start completion: function [cmb association] = IAMB( data, targetindex, THRESHOLD)
%function [cmb association] = IAMB( data, targetindex, THRESHOLD)

    
function [cmb association] = IAMB( data, targetindex, THRESHOLD)
%function [cmb association] = IAMB( data, targetindex, THRESHOLD)

%Performs the IAMB algorithm of Tsmardinos et al. (2003)
%from "Towards principled feature selection: Relevancy, filters and wrappers"

if (nargin == 2)
  THRESHOLD = 0.02;
