[Split ratio] 0 and 1 should be also possible
In https://gitlab.com/php-ai/php-ml/-/blob/master/src/CrossValidation/Split.php#L34 $testSize=0
or $testSize=1
should also be possible. Especially 0
would be nice for testing purposes when all given samples shall be used as train samples.
I am new to Gitlab and do not know how to create a fork or pull request for that (seems to me that this is disabled for this repository).
