For the model logit(T) = a +x, let (x, y) denote the x and y values for subject i, i = 1,..., N. Suppose y = 0 for all x below some point and y; = 1 for all x above that point. Explain intuitively why B =

c. (Note: In technical terms, the sufficient statistics are y, for a and xy; for . For a given yi, xy; takes its maximum possible value for this assignment of {y;} to fixed {x}.)
