    Checks whether the length of the `*args` argument passed into a function
    has at most `len(compat_args)` arguments and whether or not all of these
    elements in `args` are set to their default values.

    Parameters
    ----------
    fname : str
        The name of the function being passed the `*args` parameter
    args : tuple
        The `*args` parameter passed into a function
    max_fname_arg_count : int
        The maximum number of arguments that the function `fname`
        can accept, excluding those in `args`. Used for displaying
        appropriate error messages. Must be non-negative.
    compat_args : dict
        A dictionary of keys and their associated default values.
        In order to accommodate buggy behaviour in some versions of `numpy`,
        where a signature displayed keyword arguments but then passed those
        arguments **positionally** internally when calling downstream
        implementations, a dict ensures that the original
        order of the keyword arguments is enforced.

    Raises
    ------
    TypeError
        If `args` contains more values than there are `compat_args`
    ValueError
        If `args` contains values that do not correspond to those
        of the default values specified in `compat_args`

    fname : str

    kwargs : dict
        The `**kwargs` parameter passed into `fname`

    `compat_args` OR `kwargs` contains keys not in `compat_args`
    ValueError if `args` contains values not at the default value (`None`)
    `kwargs` contains keys in `compat_args` that do not map to the default

    Validate the keyword arguments to 'fillna'.

    This checks that exactly one of 'value' and 'method' is specified.
    If 'method' is specified, this validates that it's a valid method.

    Parameters
    ----------
    value, method : object
        The 'value' and 'method' keyword arguments for 'fillna'.
    validate_scalar_dict_value : bool, default True
        Whether to validate that 'value' is a scalar or dict. Specifically,
        validate that it is not a list or tuple.

    q: float or iterable of floats
        A single percentile or an iterable of percentiles.

    Returns
    -------
