Dear Anupam, I may be wrong, but I don't think that there's any standard method to use in plotting with case weights. I can think of two approaches, however: (1) If you have a large sample, and if the range of the weights isn't too large, you could sample your observations with probability of i

I am trying to make plots that take into account survey weights. This a survey of the US population. To start with I want to explore the data using pairs, plot, coplots and lattice. Are there specialized methods that handle survey weights for plotting? Any pointers? Anupam. [[alternati
