Implements Bayesian estimation and inference for alpha-mixture survival models,
  including Weibull and Exponential based components, with tools for simulation and posterior 
  summaries. The methods target applications in reliability and biomedical survival analysis.
  The package implements Bayesian estimation for the alpha-mixture methodology introduced in 
  Asadi et al. (2019) <doi:10.1017/jpr.2019.72>.

Quantile regression with fixed effects solves longitudinal data, considering the individual intercepts as fixed effects. The parametric set of this type of problem used to be huge. Thus penalized methods such as Lasso are currently applied. Adaptive Lasso presents oracle proprieties, which include Gaussianity and correct model selection. Bayesian information criteria (BIC) estimates the optimal tuning parameter lambda. Plot tools are also available.

Datasets to Accompany S. Weisberg (2014, ISBN: 978-1-118-38608-8), 
 "Applied Linear Regression," 4th edition.  Many data files 
 in this package are included in the `alr3` package as well, so only one of them 
 should be used.

Alternating least squares is often used to resolve
        components contributing to data with a bilinear structure; the
        basic technique may be extended to alternating constrained
        least squares.  Commonly applied constraints include
        unimodality, non-negativity, and normalization of components.
        Several data matrices may be decomposed simultaneously by
        assuming that one of the two matrices in the bilinear
        decomposition is shared between datasets.

Using of the accelerated line search algorithm  for simultaneously diagonalize a set of symmetric positive definite matrices.
