Penalized Likelihood Estimation under the Joint Cox Models Between TTP and OS for Meta-Analysis (joint.Cox)
Perform regression analyses under the joint Cox proportional hazards model between TTP and OS for meta-analysis. The method is applicable for meta-analysis combining several studies or for cluster survival data.
EM Algorithms for Estimating Item Response Theory Models (emIRT)
Various Expectation-Maximization (EM) algorithms are implemented for item response theory (IRT) models. The current implementation includes IRT models for binary and ordinal responses, along with dynamic and hierarchical IRT models with binary responses. The latter two models are derived and implemented using variational EM.
Continuous Associated Kernel Estimation (Conake)
Continuous smoothing of probability density function on a compact or semi-infinite support is performed using four continuous associated kernels: extended beta, gamma, lognormal and reciprocal inverse Gaussian. The cross-validation technique is also implemented for bandwidth selection.
