Seeking PDF instructions on Excel Analysis ToolPak VBA

Can someone here please point me toward a good PDF about using Excel Analysis ToolPak VBA? I do most of my Excel work in VBA, instead of using macros, and would like to find good documentation on using VBA to access Excel's statistics features.

I don't always have Internet access when on the job, so I prefer instructions in PDF form that I can download to my notebook computer. Thanks.
