Re: [R] Using the effects package to plot logit probabilities

Dear Abraham, It's not entirely clear to me what you want to plot. If you want the "effect display" for each predictor holding the others to typical values, plot(allEffects(md1)) will do that. But you appear to want to plot fitted probabilities for combinations of the predictors even though the

With multiple predictors, I feel that predict ends up being less elegant. Plus, I've found a lot of the simple log-odds plots available in the effect package to be simple and easy to use as compared to base predict. On Mon, Aug 13, 2012 at 3:01 PM, Bert Gunter wrote: > Why not use > > ?predict.g

Dear Abraham, I must admit that I don't really follow what you want to do. Disregarding the fact that the example you provide doesn't converge to a proper solution, the plot that you've requested will range over all values of bid at the median home, which is 0. You may have intended home to be
