Description: Allows the simultaneous analysis of responses and response times in an Item Response Theory (IRT) modelling framework. Supports variable person speed functions (intercept, trend, quadratic), and covariates for item and person (random) parameters. Data missing-by-design can be specified. Parameter estimation is done with a MCMC algorithm. LNIRT replaces the package CIRT, which was written by Rinke Klein Entink. For reference, see the paper by Fox, Klein Entink and Van der Linden (2007), "Modeling of Responses and Response Times with the Package cirt", Journal of Statistical Software, <doi:10.18637/jss.v020.i07>.

Title: Low-Rank Decomposition of Brain Connectivity Matrices with
Authors@R: c(person("Yikai", "Wang", role = c("aut", "cph")), person("Jialu", "Ran", role = c("aut", "cre"), email = "jialuran422@gmail.com"), person("Ying", "Guo", role = c("aut", "ths")))
Description: To decompose symmetric matrices such as brain connectivity matrices so that one can extract sparse latent component matrices and also estimate mixing coefficients, a blind source separation (BSS) method named LOCUS was proposed in Wang and Guo (2023) <arXiv:2008.08915>. For brain connectivity matrices, the outputs correspond to sparse latent connectivity traits and individual-level trait loadings.

Title: Log File Analysis in International Large-Scale Assessments
Description: Enables users to handle the dataset cleaning for
conducting specific analyses with the log files from two international
educational assessments: the Programme for International Student Assessment
(PISA, <http://www.oecd.org/pisa/>) and the Programme for the International Assessment of Adult Competencies
(PIAAC, <http://www.oecd.org/skills/piaac/>). An illustration of the analyses can be found on the LOGAN Shiny app
