    Read SAS files stored as either XPORT or SAS7BDAT format files.

    Parameters
    ----------
    filepath_or_buffer : str, path object, or file-like object
        String, path object (implementing ``os.PathLike[str]``), or file-like
        object implementing a binary ``read()`` function. The string could be
        a URL. Valid URL schemes include http, ftp, s3, and file. For file
        URLs, a host is expected. A local file could be:
        ``file://localhost/path/to/table.sas7bdat``.
    format : str {{'xport', 'sas7bdat'}} or None
        If None, file format is inferred from file extension. If 'xport' or
        'sas7bdat', uses the corresponding format.
    index : identifier of index column, defaults to None
        Identifier of column that should be used as index of the DataFrame.
    encoding : str, default is None
        Encoding for text data.  If None, text data are stored as raw bytes.
    chunksize : int
        Read file `chunksize` lines at a time, returns iterator.
    iterator : bool, defaults to False
        If True, returns an iterator for reading the file incrementally.
    compression : str or dict, default 'infer'
        For on-the-fly decompression of on-disk data. If 'infer' and
        'filepath_or_buffer' is path-like, then detect compression from the
        following extensions: '.gz', '.bz2', '.zip', '.xz', '.zst', '.tar',
        '.tar.gz', '.tar.xz' or '.tar.bz2' (otherwise no compression).
        Set to ``None`` for no decompression.
        Can also be a dict with key ``'method'`` set to one of {``'zip'``,
        ``'gzip'``, ``'bz2'``, ``'zstd'``, ``'xz'``, ``'tar'``} and other
        key-value pairs are forwarded to ``zipfile.ZipFile``,
        ``gzip.GzipFile``, ``bz2.BZ2File``, ``zstandard.ZstdCompressor``,
        ``lzma.LZMAFile`` or ``tarfile.TarFile``, respectively.
        As an example, the following could be passed for faster compression
        and to create a reproducible gzip archive:
        ``compression={'method': 'gzip', 'compresslevel': 1, 'mtime': 1}``.

    Returns
    -------
    DataFrame, SAS7BDATReader, or XportReader
        DataFrame if iterator=False and chunksize=None, else SAS7BDATReader
        or XportReader, file format is inferred from file extension.

    See Also
    --------
    read_csv : Read a comma-separated values (csv) file into a DataFrame.
    read_excel : Read an Excel file into a pandas DataFrame.
    read_spss : Read an SPSS file into a pandas DataFrame.
    read_orc : Load an ORC object into a pandas DataFrame.
    read_feather : Load a feather-format object into a pandas DataFrame.

    Examples
    --------
    >>> df = pd.read_sas("sas_data.sas7bdat")  # doctest: +SKIP
