Re: st: which statistical analysis to use

[David Hoaglin <dchoaglin@gmail.com>]

Deborah,

By an interesting coincidence, the issue of Computational Statistics &
Data Analysis that arrived today contains a paper on ranking data:

Lee PH, Yu PLH. Mixtures of weighted distance-based models for ranking
data with applications in political studies.  Computational Statistics
& Data Analysis 2012; 56:2486-2500.

That paper is probably not directly relevant to the analysis that you
are trying to do, but its list of references may be helpful in making
contact with that literature.  In particular, I noticed two books:

Marden JI. Analyzing and Modeling Rank Data. Chapman and Hall, 1995.

Fligner MA, Verducci JS (eds.). Probability Models and Statistical
Analyses for Ranking Data. Springer-Verlag, 1993.

I hope this information is useful.

The other skills (which they find less important) are not given any score (they are zero in my data). The data for that question thus looks somewhat as follows (example for 3 companies, one row per company:
