| Abstract | ||
| .Abstract This research is devoted to study of two-way Multivariate repeated measurements analysis of covariance model (MRM ANCOVA), which contain two between-unites factors (factor A and factor B), two within-units factors (Time and Day) and two covariates (Z_1,Z_2 ) .For this model the two covariate is time-independent, that is measured only once and one univariate random effect. the test statistics of various hypotheses on between-unites factors, within-units factors and the interaction between them are given and including the application to study the assessment of water quality of the northern part of shatt AL-Arab river and determine its suitability for aquatic environment, drinking and irrigation, through studying some variables that have the greatest effect on water quality which is avariable in the experiment during one year through twelve months. | ||
