Dear all, I am applying the StructTS function in ts-package. For some time series the program terminates and the following error appears: Error in optim(init[mask], getLike, method = "L-BFGS-B", lower = rep(0, : L-BFGS-B needs finite values of fn Do someone know what do I have to adjust in the original time series to avoid this error? It works fine for some subsets of the time series only. Thank you in advance. --- Gregor Gawron -.-.-.-.-.-.-....

...out. However, I am having some problems smoothing and plotting the smoothed version. > A <- as.ts(read.table(choose.files())) > x <- as.ts(A[,10]) > plot(x) > > plot(smooth(x)) plot(smooth(x)) looks exactly like plot(x). Also, > StructTS(x) Error in optim(init[mask], getLike, method = "L-BFGS-B", lower = rep(0, : L-BFGS-B needs finite values of 'fn' The HoltWinters smoothing or the Kalman smoothing don't work either for various errors... I'm not quite sure what's wrong. Thanks. -- View this message in context: http://www.nabble.com/T...
