Correlation of Wafer Acceptance Test (WAT) and In-line Manufacturing Process ….. Inline n Inline 1 Inline 2 Inline 3 WAT 5 • Objective • Analyze and monitor sensitivity of WAT parameter to In-line then keep WAT unchanged by adjusting In-line shift. • Multiple Regression Model (MRM)
• Example: Let the number of men and women entering a post office in a certain interval be two independent Poisson random variables with parameters l and m , respectively. Find the conditional probability function of the number of men given the total number of persons. Solution: Let N, M, K be the total number of men, women, and persons entering the post office. Note that K = M+N and M, N are independent. So we have K is also Poisson with parameter l+m. pN|K(n|k) = P(N=n)P(M=k-n)/P(K=k)= 12 - 17
