Webhas been recent progress on adapting MCMC methods to sparse high-dimensional logistic regression [29], while another common alternative is to instead use continuous shrinkage-type priors [10, 52]. A popular scalable alternative is variational Bayes (VB), which approximates the posterior by solving an optimization problem. WebAfter that, the estimated value for the logistic regression model is found by solving the equation logit(P(CHD=1)) = 0 + 1 * CAT. It is possible to model coronary heart disease (CHD) using linear regression if one first converts the probability of CHD onto a continuous scale using the logit function.
