Expanding.min(numeric_only=False, *args, engine=None, engine_kwargs=None, **kwargs)[source]

Calculate the expanding minimum.

Parameters

numeric_only:bool, default False

Include only float, int, boolean columns.

New in version 1.5.0.

*args

For NumPy compatibility and will not have an effect on the result.

Deprecated since version 1.5.0.

engine:str, default None

• 'cython' : Runs the operation through C-extensions from cython.

• 'numba' : Runs the operation through JIT compiled code from numba.

• None : Defaults to 'cython' or globally setting compute.use_numba

  New in version 1.3.0.

engine_kwargs:dict, default None

• For 'cython' engine, there are no accepted engine_kwargs

• For 'numba' engine, the engine can accept nopython, nogil and parallel dictionary keys. The values must either be True or False. The default engine_kwargs for the 'numba' engine is {'nopython': True, 'nogil': False, 'parallel': False}

**kwargs
