Estimation, Testing, and Prediction Regions of the Fixed and Random   Effects by Solving the Henderson's Mixed Model Equations
  We present a brief overview of the methods for making statistical inference (testing statistical hypotheses, construction of confidence and/or prediction intervals and regions) about linear functions of the fixed effects and/or about the fixed and random effects simultaneously, in conventional simple linear mixed model. The presented approach is based on solutions from the Henderson's mixed model equations.
