8.1 Suppose that you want to design an experiment to fit a logistic regression model in two predictors. A first-order model is assumed. Based on prior information about the experimental situation, reasonable ranges for the model parameters are 0.5 <β0<5 2<ßx<6 \<β2<4 and the normal distribution is a reasonable prior. Find a Bayesian Doptimal design with 10 runs for this experiment.
