Hello All, I've problems to interpret the contourplot for a binary response dependent variable. For example, I ploted the survived probability for the titanic3 dataset, http://www.geocities.com/useebi/data/CondenContour.jpeg Trellis displayed two panels of contour, one for dead and one for alive. However, the contours between the two panels didn't conform to the rule of prob(dead) = 1 - prob(alive). How I should read the contours? What I did wrongly? Is there an example that I could follow? Thanks! marco --------------------------------- [[alternative HTML version deleted]]

What I did wrongly?Hard to say, since we have no idea what you actually did. As the footer of every r-help message says: PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. -Deepayan> Is there an example that I could follow? > > Thanks! > marco
