Some Remarks on One-way Repeated Measurements Model for Unbalanced Data

ABSTRACT

In this paper, we consider the one-way repeated measurements model for unbalanced data (where the number of observations is unequal in each levels). We then discuss method to estimate the parameters of the model ,and introduce some properties of estimators. As practical research , the objective of the experiment is to study the effect of the experimental factors and their interactions on the production of date palm, cultivar El Halawi. The experiment included the factor of irrigation method with three treatments: drip irrigation, basin irrigation, and the regular tidal method, while the irrigation interval factor included three treatments: 3, 6 and 9 days.
