31. Randomization allows to give an estimate of the variance while still using quasi-random sequences.32. PaX leaves a portion of the addresses, the MSBs, out of the randomization calculations. 33. To avoid this, randomization was replaced by a degree of difficulty in accomplishing the feat. 34. Importantly, independent laboratories should prepare the solutions and encode to ensure proper blinding and randomization . 35. The randomization was stopped so all patients enrolling on the trial will receive the antibody therapy. 36. As stated, prelink and per-process library address randomization cannot be used in conjunction. 37. In comparison, the current predominant design is for consent to be solicited prior to randomization . 38. One such assignment mechanism is randomization . 39. He also helped to introduce the concept of restricted randomization , which he called constrained randomization. 40.
