• Survival analysis is a widely used method to establish a connection between a time to event outcome and a set of potential covariates. Our results show that this parametric bootstrap procedure is a powerful tool to study samples with scarcity of data. In the case of logit link, one can focus on the treatment effect on the marginalized odds instead of the odds of the marginalized event so that the product method would be equivalent to the difference method. The International Journal of Biostatistics (IJB) seeks to publish new biostatistical models and methods, new statistical theory, as well as original applications of statistical methods, for important practical … The performance of the algorithm is assessed via a simulation study, which includes also a comparative study with alternatives when available in the literature. Annals of Biometrics & Biostatistics is a peer reviewed, multidisciplinary, international open access journal. In this paper, the application of Generalized Additive Model for Location, Scale and Shape (GAMLSS) and the use of finite mixture model for GAMLSS will be proposed as a solution to the problem of overdispersion.

Candidate algorithms may range from a basic Cox model to tree-based machine learning algorithms, assuming all candidate algorithms are based on the proportional hazards framework. In order to optimize the finite sample coverage of the nonparametric bootstrap confidence intervals, we propose a selection method for this sectional variation norm that is based on running the nonparametric bootstrap for all values of the sectional variation norm larger than the one selected by cross-validation, and subsequently determining a value at which the width of the resulting confidence intervals reaches a plateau. 1, Art.

The International Journal of Biostatistics Volume 5, Issue 1 2009 Article 3 Fitting Smooth-in-Time Prognostic Risk Functions via Logistic Regression James A. Hanley∗ Olli S. Miettinen† ∗McGill … An extensive simulation study is conducted and suggests that the presented method works well in practical situations. More specifically, we incorporate the robust mean shift outlier handling mechanism into the multiple QTL mapping regression model and apply LASSO regularization concurrently to the genetic effects and the mean-shift terms through the flexible extended Bayesian LASSO (EBL) prior structure, thereby combining QTL mapping and outlier detection into a single sparse model representation problem. About the journal Biostatistics publishes papers that develop innovative statistical methods with applications to the understanding of human health and disease, including basic biomedical sciences … Top cited research Biostatistics … Many different algorithms have been proposed for survival prediction. We compare the performance of the proposed super learners with existing models through extensive simulation studies.

The interpretation of estimated mixed-effects models is challenging since changing the structure of one set of effects can lead to different choices of important covariates in the model. The proposed procedure performs model selection in both linear and nonlinear models. We empirically evaluate the performance of the existing and proposed methods using a simulation study and illustrate the practical aspects of the procedures by a re-analysis of the respiratory sub-item in functional rating scales of patients suffering from Amyotrophic Lateral Sclerosis (ALS). It is based on Bayesian Information criteria whose penalties are adapted to mixed-effects models.
