trdel

The dataset <code>trdel</code> contains data from a paired comparison
study to investigate which of five training delivery modes trainees prefer
(Schoell and Veith, 2011).
The modes were computer-based (<code>CO</code>), TV-based (<code>TV</code>), paper-based (<code>PA</code>),
audio-based (<code>AU</code>) and classroom-based (<code>CL</code>) training. Study
participants were unemployed persons in the labour market training of
the Austrian labour market service (AMS). To account for trainee
characteristics that might affect the preference order the variables
gender, age, and learning personality type were recorded. These variables were
coded as <code>sex</code> (1 male, 2 female), <code>age</code> (numeric in years), <code>ltype</code> (1
accomodator, 2 diverger, 3 converger, 4 assimilator). The learning personality
types were identified from a questionnaire.

datasets

Generates design matrix for analysing real paired comparisons and derived paired comparison data (Likert type items/ratings or rankings) using a loglinear approach.  Fits loglinear Bradley-Terry model (LLBT) exploiting an eliminate feature.  Computes pattern models for paired comparisons, rankings, and ratings.  Some treatment of missing values (MCAR and MNAR). Fits latent class (mixture) models for paired comparison, rating and ranking patterns using a non-parametric ML approach.
