Problem 1. The dataset iris. csv gives Fisher's famous Iris dataset after removing one of the three flower species. Answer the following. 1. Fit a frequentist logistic regression on Species against the four predictors and show the summary output (estimate of coefficients, standard errors, etc. ) if possible. What do you observe? Do you see any problems? 2. Fit a Bayesian logistic regression on Species against the four predictors using vague priors (say, Bi ~ N(0, o2 = 1000) for i = 0, 1, 2, 3, 4). Provide a summary of the coefficients along with their 95% credible intervals. 3. Re-run the Bayesian LR model with B; ~ N(0, 1) priors. Compare the answers of the 3 parts. Are the Bayesian solutions more meaningful
