The irrigation return influent is transferred into ground water that can be further developed and utilized, which should be involved in the total water resource and should not be considered repeated water.

Objective: In this article,a repeated measures data was analyzed in order to explain the application and characteristic of mixed effects linear model which was compared with single effects analysis of variance in order to account for it s use.

Purpose Main effect is usually misconceived in repeated measures ANOVA(analysis of variance).

First, the repeated measures model is introduced concisely by using an example of clinical trial.

Mixed linear model and its application to repeated measurements in single-sample;

Based on the trendan alysis of residuals obtained by fitting a linear regressionmodel,a method is suggested for testing the linear regression relation ship with and with out repeated measurementsre spectively .

In many fields of medical studies, the analysis and design of repeated measurements data are often come across.

Objective Probing into the correlation structures within subject, and research into the applicability, characteristic, selected thereunder and so on about different statistical methods for repeated measure data.

But in many papers,the use of mixed effects model is in the single variable repeated measurement and the correla.
