Hello, I use nnet to do prediction for a continuous variable. after that, I calculate correlation coefficient between predicted value and real observation. I run my code(see following) several time, but I get different correlation coefficient each time. Anyone know why? In addition, How to calculate prediction accuracy for prediction of continuous variable? Aimin thanks, > m.nn.omega

Hello, I have a question about splitting label in regression tree. for example, by using the following command plot(m.regression.tree.pr,uniform=T,margin=0.05,branch=0.7,compress=F) text(m.regression.tree.pr,pretty=0) I get a tree with one label in some splitting node like this bcu<0.004969 Now I want to set up bcu<0.0050, i.e. just get 4 number after decimal. Does anyone know how to set

Hello All, I'm having a weird problem when connecting up to a TA 750 from adtran. The problem I'm seeing is that the third wire on my 66 block is behaving as the tip (or ring) for every extension.
