Abstract:
انصب هدف الرسالة في امرين على درجة من الاهمية وهما اولا دراسة تحليلية لطبيعة التجارب بالقياسات المكررة لعدة تصاميم والتركيز على التجارب العاملية والعاملية المتداخلة وبناء النماذج الرياضية الخطية لهذه التجارب الذي يعتمد علية التحليل. لقد تم استعمال الط | Focused message in a two objective on the degree of importance and them first analytical Study to the nature of repeated measurements experiments for several designs and focus on the Nested - Factor Experiments and build linear mathematical models for these experiments upon which the analysis. It has been used several methods parametric to analysis these types of designs. which are difficult to analyze in sometimes because of the not provide conditions analysis of variance for repeated measurements experiments. The second objective of the message is application this kind of experience in the medical sector by studying a particular phenomenon characterized by a repeated measurements represented Thalassemia in Wasit province. Where he was studying three types of experiments the existence of a repeated measurements It is experiments with a one factor and have a repeated measurements on the same element, Factorial Experiment qxp repeated measurements on one factor, and Nested - Factorial experiment repeated measurements on one factor. As well as the use of methods of transfer to ranks (Rank Transformation) as one of the solutions that have made conditions analysis of variance to experiments measurements repeated of (distribution Normal random and independent for experimental error, homogeneity of variances, the lack of correlation between the averages and variances, spherical). Satisfactory because the transfer to ranks makes the data on the most homogeneous and normal, although we have identified a condition analysis of variance exclusively for the purpose of comparison by the value of the P - Value. The data can be described about Thalassemia in Wasit as follows : were assessed Standards quantities of iron (Fe) in the letter, groups this data classified into two groups, the first group included 20 patients (10 males, 10 females) and who have been subjected to the first chemotherapy (axja) by mouth for four treatment cycles (treatments) of each period lasts 30 days , and the second group included 20 patients (10 males, 10 females) who were exposed to second chemotherapy (Desferal) by injection into the skin or muscle of four treatment cycles (treatments), where each treatment cycle lasts 30 days. the most important conclusions that have been reached is that the Data Transformation by ranks led to the provision of analysis of variance conditions for experiments repeated measurements distribution the normal errors and homogeneity of variances and correlation between mean and variance, as well as a spherical condition. Through the four applications we believe that giving the first dose of the drug to patients has led to high amounts of iron to patients over time and this type of treatment is used when high amounts of iron ratio. As well as when you give the second dose of the drug to patients has led to high amounts of iron to patients over time, but at rates lower than the first treatment and this type of treatment is used when a weak proportion of iron in the blood of the patient.
