Each iteration adds independent variable count rows. The columns are as follows: [0] Iteration Step [1] Variable index [2] variable selection where 0 means excluded and 1 means included. [3] holds the normalized coeffients and Fourth column the [4] corresponding t-values for each coefficient [5] two tailed p-values. Bigger p-values suggest the probability that the model would better, if the variable would be excluded.
