Among them, D(A_i) is the actual data that the factor A_i conforms to the normal distribution when calculating the correlation coefficient. The actual data value D(A_(n+1)) of the target factor A_(n+1) is set to D(P).
Where d (a_i) is the factor a used to calculate the correlation coefficient_ I actual data conforming to normal distribution. Objective factor A_ The actual data value D (a_ (n + 1)) of (n + 1) is set to D (P).
In which D(A_i) is the actual data that the factor A_i accords with the normal distribution when calculating the correlation coefficient. The actual data value d (A_(n+1)) of the factor a _ (n+1) is set to D(P).
