Subject: New Extension Module on SPSS Developer Central
Content-Type: text/plain; charset="utf-8"
I have uploaded a new Extension command to SPSS Developer Central (www.spss.com/devcentral).
Extension commands require SPSS 16 or, better, SPSS 16.0.1, the appropriate plugin, and Python or R.
This module, named propor, provides the PROPOR command, which displays binomial and Poisson confidence intervals for proportions and, if multiple proportions are specified, it displays confidence intervals for the differences.
Extension commands, new in SPSS 16, allow authors to define their own SPSS-style syntax and implement commands in Python or R with output going to the Viewer.
For example, after installing this module, you can run
PROPOR NUM=x DENOM=y /LEVEL ALPHA=.1.
just as if this were a built-in command. Extension commands are loaded automatically when SPSS starts.
This module is new; comments appreciated.
