The Regression analysis is considered as a basic element of statistics science elements, and it is an important style of applied statistics when studying different social and economical phenomena. As well as it is considered the most statistical method used in different sciences and fields, and it determines in clear picture the relations among the variables in the form of equation replaced from the degree of parametric on the strength and the importance of this relationship .And ;also it repots the degree of prediction and response ;also ,it is necessary in regression planning and making decisions for finding regression equation .And it is one of modern styles which tak observable caring especially in artificial neural networks. Our main aim is using neural networks in regression in special visage comparison of neural networks styles with classical styles in analyzing linear and non linear regression of prediction in monthly production of electric energy for the seven years i .e from 2006 to 2012 . The research includes the method of analyzing prediction and regression by using the two methods, classic and neural networks and making comparison between the two methods , the 1st method involve the linear model by using the data of chemical operation as a dependent variable 7 reaction time ,temperature as an independent variables for 2 years while the 2nd used the data for seven last years to reach the best method in evaluating statistical parameters , to support the research we generate three types of data one for simple linear regression , 2nd for time series and 3rd for non liner data. The results prove that neural networks are the best method in non linear models while the reverse in the linear models explaining best ways their results.
Abstract
Travel Time estimation and reliability measurement is an important issues for improving operation efficiency and safety of traffic roads networks. The aim of this research is the estimation of total travel time and distribution analysis for three selected links in Palestine Arterial Street in Baghdad city. Buffer time index results in worse reliability conditions. Link (2) from Bab Al Mutham intersection to Al-Sakara intersection produced a buffer index of about 36% and 26 % for Link (1) Al-Mawall intersection to Bab Al- Mutham intersection and finally for link (3) which presented a 24% buffer index. These illustrated that the reliability get worst for link

Mixed-effects conditional logistic regression is evidently more effective in the study of qualitative differences in longitudinal pollution data as well as their implications on heterogeneous subgroups. This study seeks that conditional logistic regression is a robust evaluation method for environmental studies, thru the analysis of environment pollution as a function of oil production and environmental factors. Consequently, it has been established theoretically that the primary objective of model selection in this research is to identify the candidate model that is optimal for the conditional design. The candidate model should achieve generalizability, goodness-of-fit, parsimony and establish equilibrium between bias and variab

Predictability of School Environment in the tendency to aggressive behavior among high primary school students. This study aimed at exploring the Family and school environment predictability of the tendency to aggressive behavior among high primary school students in Irbid Second Directorate of Education. The study sample consisted of 784 male and female students in the high-primary schools of Irbid Second Directorate of Education, chosen as on random cluster sampling method. Three aspects of school environment had the predictability of the tendency to aggressive behavior. The academic orientation of students explained 9.9% of the total variation in the dependant variable while the relationships between peers explained 1.6% and the teach

This research aims at identifying the effect of problem solving strategy on the achievement of Kurdish language grammer of femal students at the fourth preperatory school. To achieve the study aims , the researcher has chosen intentionally this sample to apply the experiement . The study sample cosists 0f (58) female students distributed randomly on two groups. The experiemental group is taught according to problem- solving strategy and it is (29) female students, while the control group which is also (29) individuals is taught according to the traditional way of teaching . The two groups have been matched statistically in term of age , the academic achievement for the father and mother , intelligence, and the linguistic ability. The exp

The effect of partial substitution for veal with TSP quality, sensory characteristics such as color and homogenizing of the stuffing, taste, flavor, juiciness and overall acceptability was evaluated by taste panel. The obtained results showed that product prepared with replaced 15 and 20% were acceptable by panel taste without significant differences compared to control. The values of taste panel score dropped as the rate partial replacement increased a level of TSP 25 and 30% as compared to control. It can be concluded the possibility of using manufacture
