    El Modelo de Respuesta Nominal: Aplicación a datos educacionales
    (Pontificia Universidad Católica del Perú, 2019-07-17) Rivera Espejo, José Manuel; Tarazona Vargas, Enver Gerald
    This thesis focuses its e orts on presenting and studying the Nominal Response Model or NRM (Bock, 1972, 1997), in the context of the Item Response Theory (IRT). Simulation studies are carried out to determine the quality of the recovery of the parameters of the model, under the Classic (MML) and Bayesian (MCMC) aproach and nally, the studied model was applied to an random, representative and anonymous sample of 1641 teachers from the Basic Regular Education modality of the english specialty, who were exposed to the Reading-Comprehension sub-test of the \Concurso de Nombramiento 2015". Related to the simulation, we found the bayesian method is a good substitute for the classic counterpart, because it recovers in a similarly satisfactory fashion the parameters of the items; however, the main disadvantage was that the process was between 620 to 14; 100 times slower than the classical approach, despite the special emphasis on making the MCMC processes parrallel. Related to the results of the implementation of the model on real data, the NRM: (i) it facilitates the recovery of a greater proportion of information available in the items, compared to dichotomous response models (Bock, 1972; Thissen, 1976; Levine y Drasgow, 1983; Thissen y Steinberg, 1984), (ii) it allows to nd the implicit order in initially not ordered categorical data (Samejima, 1988; Bock, 1997) and (iii) it provided relevant information for the examination of the quality of an item (Thissen et al., 1989), specially in two fronts: (a) it allowed the identi cation of useless or forced alternatives and (b) it allowed the identi cation of alternatives that could be collapsed, given that these alternatives registered a similar topics.
