We are currently using the function pointwise(predict(. . . ., se.fit=T)) with the glm function in S-Plus to obtain confidence intervals for the predicted values from fitting a generalized linear mo

Does anyone have a program or know where I can find a program for plotting contour lines on a ternary plot. For example, in mixture experimental designs we usually present the response surface contou

A while ago we asked the s-news list regarding the calculation of the Wald asymptotic confidence intervals on Splus. Hugh Jones replied that we should evaluate the pointwise() function itself in orde
