[Dishie2498]

[EtienneCmb]

Thanks @Dishie2498, great work !

Could please add the following :

core/it.py

Copnorm functions are related to information theoretical measures. Let's cut ctransform, copnorm_1d and copnorm_nd from the oinfo file to it.py

metrics/oinfo_zerolag.py

• Rename conn_oinfo_jax function to oinfo_zerolag

core/init.py

Import functions :

from .combinatory  import combinations  # noqa
from .it import ent_g,  copnorm_1d, copnorm_nd  # noqa

metrics/init.py

from .oinfo_zerolag import oinfo_zerolag  # noqa
