I did a quick skim over the source code for this and on that basis it looks good to me.

One thing I noticed: please use the pow2() inline function already in misc.h instead of adding a new macro to do the same thing.  Using a macro just makes optimization harder for the compiler, at least where the argument is more complicated than a single variable name.

The attached patch implements a simplified version of the reliability command.

It supports /MODEL=ALPHA and MODEL=SPLIT and SUMMARY=total.

Cronbach alpha is reported for all options.

It would be great to see Cronbach Alpha Equivalent implemented.
