python - 从(古代)SAS 版本 6(适用于 Python/R)读取 .ssd01 数据文件

Question

在分析 somewhat old academic paper 中的一些数据时，我收到了一些由更旧的软件生成的数据文件，即已有 20 多年历史的 SAS 版本 6(.ssd01 扩展名)。

如何将此文件转换为现代格式以便使用 R、Python 等进行分析？如果该过程不需要获得 SAS 许可证或其他商业软件，则可获得奖励(赏金)点。

提示:

• Reading SAS® data sets with a filename extension such as .ssd01 or .ssd
• Pandas 有一个 read_sas method ，但仅适用于 SAS 版本 7 和更高版本的数据 (*.sas7bdat)
• R 对 .sas7bdat 有类似的导入函数，但这也不适用于此版本:Read SAS sas7bdat data into R

以下是这些文件，以防有人想动手(不，它们不是病毒，只是上述论文中的数据):

swallco.ssd01, swallpd.ssd01

Answer 1

我刚刚从 https://www.stattransfer.com 获取了该软件的 Windows 64 位版本的演示版并将其应用到您的第一个文件，要求 csv 输出。这是结果的前几行。

我不知道这有多好! :) 不，我与任何制造或销售此产品的公司没有任何关系。而且，不，我以前从未尝试过。你现在(几乎)和我一样知道了关于它的一切。

祝你好运。
