Confidence Interval for the Variance Component in a Unbalanced One-way Random Effects Model

  • 발행 : 2002.10.31

초록

Two methods are proposed for constructing a confidence interval on the among group variance component in a unbalanced one-way random effects model. Computer simulation is used to compare these methods with alternative procedures. The results indicate that the method1 and methods2 perform well over small group size and large sample size respectively.
