Figure BDA0003140736000000101
it should be explained that when AB is used i <AB m -2*AB σ When the stimulation is positive, the probability that the arrow appears at the position of the material which is positive stimulation is 0, and when the stimulation is AB m -2*AB σ <AB i <AB m -AB σ When the stimulation is performed, the probability that the arrow appears at the position of the original positive stimulation material is 1/8, and when the stimulation is performed, the arrow appears at the position AB m -AB σ <AB i <AB m When the stimulation is positive, the probability that the arrow appears at the position of the material which is positive is 3/8, and when the stimulation is AB m <AB i <AB m +AB σ When the stimulation is positive, the probability that the arrow appears at the position of the material which is positive is 5/8, and when the stimulation is AB m +AB σ <AB i <AB m +2*AB σ When the stimulation is performed, the probability that the arrow appears at the position of the original positive stimulation material is 7/8, and when the stimulation is performed, the probability that the arrow appears at the position of the original positive stimulation material is AB m +2*AB σ <AB i If so, the probability that the arrow appears at the location of the original positive stimulus material is 1.
