function [ydep, xdata] = mylagv(data, lagv, coldep, delay);
% Creates a lag structure of data for variables lages on the columns
% Input: data, lagv, lagv must be of dimension 1:columns of data
% coldep: column of dependent variable in data
% delay factor:forecast one period (0), or one week or one month
% Output:  ydep and xdata: dependent variable and independent variables
