Issue:
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
