...Linux (Fedora Core 1). R works perfectly on it under Linux. I've downloaded and re-installed the binaries on both machines several times, so I don't think I have a corrupted download. Any ideas on how to diagnose (and solve) this problem would be greatly appreciated. Kent -- Kent E.

...) to compare the models. random = a.max + a.qe +lcp ~ 1 | bench works fine, but I can't figure out how to drop nested terms from only some of the coefficients. Any help (including pointers to appropriate pages in Pinheiro and Bates) will be much appreciated. Thanks. Kent -- Kent E.

Hello, and please excuse this off-topic question, but I have not been able to find an answer elsewhere. Consider a value Z that is calculated using the product (or ratio) of two means X_mean and Y_mean: Z=X_mean*Y_mean. More generally, Z=f(X_mean, Y_mean). The standard error of Z will be a function of the standard errors of the means of X and Y. I want to calculate this se of Z. Can someone
