Item Response Theory Modeling of High School Students’ Behavior in a High-Stakes Exam

Helen Gomes, Raul Matsushita, Sergio Da Silva
We put forward a model based on item response theory that highlights the role of latent features called “proficiency” and “propensity”. The model is adjusted to data from the decisions made in a high-stakes exam taken by 10,822 Brazilian high school students. Our model aims to recover infor-mation regarding the role the latent features (proficiency and propensity) play in a decision. We find that the decision of responding or not

Application of the Power Series Probability Distributions for the Analysis of Zero-Inflated Insect Count Data

Remi Mrume Sakia
Excess number of zeros (zero inflation, ZI) in count data is a common phenomenon which must be addressed in any analysis. The extra zeros may be a result of over-dispersion in the data. Ignoring zero-inflation can result in biased parameter estimates and standard errors. Over-dispersion is also associated with a zero-inflated data. Depending on the selected model, different results and conclusions may be reached. In this paper

Effect of Slope and Packing Ratio on the Behavior of Matchsticks Burnings

Priya Karna, Roma Karna, Sunil Karna
The experiment was conducted to demonstrate the behavior of fire propagation in wildlands using a matchsticks forest model. A model forest was designed on a flame resistant clay, on top of which matchsticks were inserted and kept vertical to the ground by keeping space between them constant with the help of aluminum grid. The data for distance travelled by fire with time were taken at wide ran
