Thank you for the new transformer, just some comments that i left
would be good to add a test for it , simple one to call it on random data

Are there any more changes needed?

[hadifawaz1999]

i would like your input @TonyBagnall on this given you made the feature request

[aryanpola]

@hadifawaz1999 I've added the test for normalise class. Any changes to be made?

[hadifawaz1999]

All changes look great thanks, could you just add the transformer to api ? then we can merge it

[hadifawaz1999]

so if am not mistaken @TonyBagnall standard would mean just zero mean and not divide by std ?

[TonyBagnall]

thanks for this, just need to either change the meaning of standardise or stick with the two allowed values, its up to you

[aryanpola]

INTERNALERROR> ImportError: cannot import name 'BaseCollectionTransformer' from partially initialized module 'aeon.transformations.collection' (most likely due to a circular import) (C:\aeon\aeon\transformations\collection\__init__.py)

@TonyBagnall can you please help with this error.

rather than

from aeon.transformations.collection import BaseCollectionTransformer
use
from aeon.transformations.collection.base import BaseCollectionTransformer

[TonyBagnall]

LGTM, thanks

all fixed
