Dear Sir/Madam,
I am stuck with a nagging problem in using R for SVM regression. My data has 5 dimensions and 400 observations. The independent variables are : Peb, Ksub, Sub, and Xtt.
The dependent variable is: Rexp.
I tried using the svm.tune function to tune the hyper parameters: gamma, epsilon and C.
I am getting the following error message: Error in predict.svm(ret, xhold, decision.values+TRUE): Model is empty! May you please help me!
