Multiple Regression

Once the dependent and independent variable are selected, the method for variables to enter can be selected or to be removed using any of the methods say stepwise, Remove, Backward or Forward. When clicked on the statistics, the estimate confidence intervals and model fit are selected and in the residuals Durbin-Watson is selected. The significance of each of these is as follows.
Estimates: They give the estimated coefficients of the regression mode. The test statistics and their significances are also obtained for each regression. Here T-test is used to see whether each b differences significantly from zero.
The correlation matrix gives the Pearson correlation coefficient between every pair of variables. It also gives the one significance of each correlation. Here we observe that the correlation is significant with p ...

Summary

The general form of the multiple regression is Y= a +b1X1 +b2X2+b3X3.+bnXn + e which can be estimated by Y= a +b1X1 +b2X2+b3X3.+bnXn, where a is the intercept and bi's are the partial regression coefficients.
Coefficient of Multiple Determination: R2 which gives the % of the variance in the dependent variable that is explained by the variation in the independent variables…

The term "regression", is mainly used to find the relationship between two or more variables used in different context. The method was first used to examine the relationship between the heights of fathers and sons. The two were related, and found that a tall father tended to have sons shorter than him; a short father tended to have sons taller than him. The height of sons regressed to the mean. The term linear regression is also referred to as the lines of regression.

Regression analysis
The change in the dependent value for a variation in the independent value is estimated in the regression analysis. Multiple regression takes into consideration all the assumptions of correlation. It takes place when the independent variable is dichotomy. In the above prescribed case, if the increase of men and women were to be considered separately; Multiple regression is used. In the case of linear correlation no power terms are found as it will not reflect curvilinear changes in independent variables. In the context of multiple regression the powers to the variables were found to represent...

The basic approach is to train an ANN unit using a set of already known set of data to predict a similar future event. In this study feed forward ANN could be used to relate the DO measured at each location to predict the other quality parameters as reported. In this method, the (DO)i is considered as the input parameter to the input-neurons which would be passed into the hidden layer of neuron set after multiplying with a correction weight (kj). The main role of the hidden neuron is to add up the weighted sum received from the input set and combines it with a bias (bj) to determine a net...

A billion dollar increase in net exports holding consumption and direct foreign investments constant leads to 0.47 billion dollar increase in GDP. Considering consumption alone, it was found out that a billion dollar increase in consumption leads to 1.43 billion dollars increase in GDP and that consumption levels explains 99.84% of the total variations in GDP [r2 (60) = 0.9984]. Further, taking foreign direct investments alone, it was found that a billion dollar increase in foreign direct investment leads to 5.33 billion dollars increase in GDP. This model was found to be significant at 5%...

Multiple Correlation and Regression
There are two variables in research: the independent and the dependent variables. If a change is one variable does not cause a subsequent change in the other, then the first is an independent variable. In the event that one causes a change in the other then the former is a dependent variable (Creswell, 2003). In this study the independent variable was psychological problems while the dependent variable was normal development.
