DOI: 10.1002/sim.9534
Abstract: When an infectious disease recurs, it may be due to treatment failure or a new infection. Being able to distinguish and classify these two different outcomes is critical in effective disease control. A multi‐state model… read more here.

DOI: 10.1117/1.jrs.13.014518
Abstract: Abstract. Generalization of the KA distribution is formulated by combining the class A and K distributions; the resulting distribution is termed as generalized KA distribution. It is obtained as a mixture of a generalized Rayleigh… read more here.

DOI: 10.1371/journal.pone.0279918
Abstract: One of the main concerns in multidimensional item response theory (MIRT) is to detect the relationship between observed items and latent traits, which is typically addressed by the exploratory analysis and factor rotation techniques. Recently,… read more here.
