SVM cross validation in e1071
Hi list,
Could someone help me to explain why the leave-one-out cross validation results I got from svm using the internal option "cross" are different from those I got manually? It seems using "cross" to do cross validation, the results are always better. Please see the code below. I also include lda as a comparison.
I'm using WinXP, R-2.9.0, and e1071_1.5-19.
Many
