Multiple Regression - Essay ExampleThey help in assessing the likely abide by of the regression coefficients in the population.Model Fit It provides a statistical test of the pretences ability to predict the outcome variable and also the hold dear of R, R2 and adjusted R2.Estimates They breach 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 uplift whether each b differences significantly from zero.Durbin Watson This test statistic tests the assumption of freelance errors. If the value is different from value Z, then it is cause of concern. When this data is run on SPSS taking Satisfaction as dependent variable and functional, Epistemic, Social, Emotional, conditional as independent variables, we get the following outputs.The first output is the Descriptive statistics.Descriptive StatisticsMeanStd.

Once the dependent and independent variable are selected, the rule 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 foll ows.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 stay fresh that the correlation is significant with p
