    How do I choose between the different cross-validation leave-out options?

Possible Solutions:

    There are many attributes that influence selection of the appropriate cross-validation scheme for a given situation:

    * The ordering of the samples in the dataset,
    * The total number of objects (and variables) in the dataset
    * The presence (or lack thereof) of replicate samples in the dataset
    * The specific objective(s) of the analysis,
    * The consequences/costs of overly optimistic or overly pessimistic results, and
    * The amount of time available to do cross-validation

    For details on the different methods, see our Wiki page: Using Cross-Validation
