Why do I get different cross-validation results from the command-line crossval routine compared to the Analysis window?<br />
<br />
===Possible Solutions:===<br />
<br />
There are two possible causes of this: <br />
<br />
'''Preprocess Option Unassigned'''<br />
<br />
The most common cause is that you have not set the same preprocessing in the crossval function (see the "preprocessing" option) as you are using in the Analysis window. You should use the preprocess function to define the same preprocessing you are using in Analysis and pass this into the crossval function via the preprocessing option. <br />
<br />
'''Preprocessing Outside Cross-Validation'''<br />
<br />
The next possible cause is that you are doing the preprocessing outside of cross-validation. Preprocessing should always be done inside of cross-validation to help avoid over-fitting models.<br />
