Step 1. for i = 1 to q do | Step 2. Compose the dataset for variable set i in including variables where j = 1 to k | Step 3. Calculate over the dataset | Step 4. Compare and with log-rank test | Step 5. Save the test score for variables in subset i as | Step 6. end for | Step 7. Eliminate rows of where the array of the row has a value of more than 0.05, | and call this new set | Step 8. Count the contribution (presence) of each variable based on its identification | number in the first k columns and save as | Step 9. Return as the variable efficiency vector |
