Suppose y = 0 at x = 0,10,20,30 and y = 1 at x = 70,80,90,100.

Explain why = infinite for the model, logit[P (Y = 1)] = + x. Report hat and its SE for the software you use.

Add two obs at x=50, y=1 for one and y=0 for the other. Report hat and its SE. Do you think these are correct? Why? What happens if you replace the two observations by y = 1 at x = 49.9 and y = 0 at x = 50.1?

please give me the answer for this.

thank you.
