When doing corp <- duplicateCorrelation(Mmatrixp, design= designp, ndups=2, spacing=32448) I got the warning message: Warning message: Too much damping - convergence tolerance not achievable in: glmgam.fit(dx, dy, start = start, tol = tol, maxit = maxit, trace = trace) Is this something to care about Best regards / Johan Lindberg

It's probably caused by one of the individual correlations converging to -1, but this won't affect the overall correlation which is a robust average. Gordon >Best regards > >/ Johan Lindberg
