Abstract
Ordinal Logistic Regression (OLR) is used to predict an ordinal structured variable given one or more independent variables. In this study, OLR used to decide the level of satisfaction on SC/ST book bank scheme (ordinal independent variable), measured on a five-point Likert type scale from “completely dissatisfied-1 through completely satisfied-5, depending on the discernment of ‘life science’ and ‘engineering students belonging to Scheduled Caste (SC) or Tribe (ST)’. Model appropriateness depends on determining which explanatory variables considered for the model and selecting the link function (complementary log-log link function used in this study). Likewise, the model fitting perceptions, the accuracy of the analysis results, and the validity of the model uncertainties, for example, the test of parallel lines, were basically evaluated for deciding on the best model. One of the principal findings was that availability of essential textbooks for free, favorable library infrastructure facilities were notably significant with the student’s opinion towards the SC/ST book bank facility. Further, respondents faced difficulties with issues such as books that were no longer circulated on time, study materials had been low standard and did not cover the syllabus.
