In this article authors derive test for structure of mean vector in model with block compound symmetric covariance structure for two-level multivariate observations. One possible structure is so called structured mean vector when its components remain constant over sites or over time points, so that mean vector is of the form 1(u)circle times mu with mu = (mu(1), mu(2), ..., mu(m))' is an element of R-m. This hypothesis is tested against alternative of unstructured mean vector, which can change over sites or over time points.
