st: New packages ?ordvar- and ?r2o- on SSC

[Mike Lacy <Michael.Lacy@colostate.edu>]

Thanks to Kit Baum, two new packages for ordinal 
response variables are available from SSC.

1) ?ordvar- calculates several related measures 
of dispersion and consensus for ordinal 
variables, along with standard errors for them.
To install, type -ssc install ordvar-

2) ?r2o- calculates an explained variation fit 
measure for ordinal response models.  To install, type ?ssc install r2o-.

Both packages treat ordinal variables without 
assumptions about inter-category 
distances.  ?r2o- requires no assumption of a 
particular distributional form, method of 
estimation, or type of response model.  The 
measures implemented in these packages are 
documented in published work, cited in their respective help files.
