摘要：
The adequacy of the Box correction factor for degrees of freedom in omnibus F tests for equality of means is investigated. A range of multivariate normal models is simulated to show the extent to which this first order correction maintains test size and power under different covariance and mean structures. A key component of the investigation involves sampling from populations which have the same correction but different covariance structures.
