Assuming the model logit[P(yi = 1)] = ????xi, you take all n observations at x0.

Find ????̂ and the large-sample var(????̂). For the Wald test, explain why the chisquared noncentrality is ????2∕var(????̂), and evaluate it as ???? → ∞. Explain how this illustrates that the Wald test in logistic regression has poor behavior when the effect is strong.
