Abstract: |
The paper is concerned with the optimal design problem of estimating linear combinations of the fixed and random effects,and predicting future observations of individual responses in a random intercept model.The variance components in the model are assumed to be known.The design criteria for the predictions are obtained from the mean squared error (MSE) of the estimator and the mean squared prediction error (MSPE) of the predictor.The exact n-point optimal designs and approximate optimal designs are discussed. |
