Hello,

I have a question in using SPSS statistics.

I use it to generate a descriptive report by going to "analyze"-"descriptive statistics"- "descriptives...". I guess there is no mistakes in these steps. However, here is what I got. Please see the attached picture.( I don't know how to insert pictures here) Why I got so many question marks which are highlighted in the red box? Also, I read the code which is highlighted in the blue box and assume it represents the sequence of the data. But it is wrong obviously. It's more like Min, Max, Mean, and Std Dev rather than "mean, std dev, min, max".

In addition, I found "2 stage least squares" only under "analyze"-"repression". Is SPSS Statistics capable doing 3 stage least squares analysis too? If so, How does it work? And is there a button as for 2sls?

Thank you very much for your reply.
