Suppose that we have a sample ((yjx;): i=1....n), where y; is a binary variable. The response probability is P(y = 1/x) = A(xB), / is a parameter, and /\\(:) is the logistic function. Then the log likelihood of the observation (y,x) is Select one: O a. xlog(/(xB)) + (1-x) log(1-A(xB)). O b. (1-x) log(/(xB)) + x log(1-A(xB)). O c. y log(A(xB)) + (1-y) log(1-A(xB)). O d. (1-y) log(/(xB)) + y log(1-A(xB)
