I'm sorry, but how is this a "software error"? Please use appropriate tags when you create posts. Post creation is set to alert people here based on the tags used. If you use relevant tags, you stand a better chance of reaching experts faster.
To perform leave one out cross-validation, train your model using all data points from your training set except one which you use for testing. Repeat until all data points have been left out and used for testing. Cross-validation is a standard machine learning procedure. As such the question is not specific to bioinformatics.
