1. Suppose y = 0 at a: = 10, 20, 30,40 and y = 1 at a; = 60, 70, 80, 90.Using software (like glrn function in R), what do you get for estimates and standard errors when you t the logistic regression model (a) to these data? (b) to these eight observations and two observations at a: = 50, one with y = 1 and one with y = 0? (c) to these eight observations and observations at a: = 49.9 with y = 1 and at a: = 50.1 with y = 0? (d) In cases (a) and (b), explain why actually the ML estimate B = 00. Why does software report such a large SE for B
